What is the difference between water pipes in series and parallel, what is the difference between parallel and series?

1. Series circuit: A circuit that combines components one by one in sequence. The characteristic is that the current flowing through one component also flows through the other. For example: small lanterns in the festival.

2. Parallel circuit: A circuit consisting of connecting components side by side. The characteristic is that the current of the main circuit is divided into two parts at the branch, and flows through each of the two branches. For example: the connection of various electrical appliances in the home.

In the series circuit, the switch is closed, both bulbs are illuminated at the same time, and both bulbs are turned off, indicating that the switches in the series circuit can control all the appliances. If one of the electrical appliances is damaged or disconnected somewhere, the whole circuit will become an open circuit, the circuit will have no current, and all the electrical appliances will stop working. Therefore, in the series circuit, several electrical appliances are involved in each other, or all Work, or all stop working.

In the parallel circuit, the switch on the trunk is closed, the switch on each branch is closed, the bulb will be illuminated, the switch on the trunk will be disconnected, the switches on each branch will be closed, and the bulb will not illuminate, indicating that the switch on the trunk can be controlled. The entire circuit, the switch on the branch can only control this branch.

Each path has a current flowing through it, so even if one branch is disconnected, the other branch will still form a path with the trunk. It can be seen that in the parallel circuit, the branches are not involved.

In short, the series is all bright, all the bad all the rest; the parallel is the dry road, the whole break, the dry road is smooth, the branches are irrelevant.

1. Series circuit: A circuit that combines components one by one in sequence. As shown in the figure, the current flowing through one component also flows through the other. For example: small lanterns in the festival.

In the series circuit, the switch is closed, both bulbs are illuminated at the same time, and both bulbs are turned off, indicating that the switches in the series circuit can control all the appliances.

2. Parallel circuit: A circuit consisting of connecting components side by side, as shown in the figure, the characteristic is that the current of the main circuit is divided into two parts at the branch, and flows through each of the two branches. For example: the connection of various electrical appliances in the home.

In the parallel circuit, the switch on the trunk is closed, the switch on each branch is closed, the bulb will be illuminated, the switch on the trunk will be disconnected, the switches on each branch will be closed, and the bulb will not illuminate, indicating that the switch on the trunk can be controlled. The entire circuit, the switch on the branch can only control this branch

3. Features of series circuit and parallel circuit:

In the series circuit, since there is only one path of the current, the current flowing from the positive pole of the power source will flow through the respective electric appliances one by one, and finally return to the negative pole of the power supply. Therefore, in the series circuit, if one of the electrical appliances is damaged or disconnected somewhere, the whole circuit will become an open circuit, the circuit will have no current, and all the electrical appliances will stop working, so in the series circuit, each of them is used. The appliances are intertwined with each other, either working all or stopping all work.

In a parallel circuit, the current flowing from the positive pole of the power supply is divided into two paths at the branch, and each current flows through it, therefore, even if one branch is disconnected, the other branch still forms a path with the trunk. It can be seen that in the parallel circuit, the branches are not involved.

4. How to judge whether the electrical appliances in the circuit are connected in series or in parallel:

Series and parallel are the two most basic forms of circuit connection, and there are certain differences between them. To determine whether the components in a circuit are connected in series or in parallel, they must grasp their basic characteristics: the specific method is:

(1) Electrical connection method: Analyze the connection method of electrical appliances in the circuit, and connect them one by one in series; parallel between the two points of the circuit is parallel.

(2) Current flow method: When current flows from the positive pole of the power supply, the current flows through each component in series; when it flows through two branches at a certain point, and finally closes together, it indicates that the circuit is connected in parallel.

The series circuit current has only one path, and there are two or more current paths in parallel.

Series connection is one of the basic ways of connecting circuit components, and refers to a circuit connection in which components or components in a circuit are arranged such that current flows entirely through each component or component without shunting.

In a series circuit, the currents on the resistors are equal, and the sum of the voltages across the resistors is equal to the total voltage of the circuit. It can be seen that the voltage on each resistor is less than the total voltage of the circuit, so the series resistor is divided.

In a parallel circuit, the voltage across the resistors is equal, and the sum of the currents across the resistors is equal to the total current (the mains current). It can be seen that the current on each resistor is less than the total current (dry current), so the shunt resistor is shunted. The series and parallel connection of resistors is like water flow. There is only one road in series. The larger the resistance, the slower the flow, the more branches in parallel, the larger the current.

By connecting two or more switches in series, a logic and circuit are formed. Assuming that the power supply is connected to both ends of the circuit, the current will only circulate when all switches are closed.

1. Series circuit: A circuit that combines components one by one in sequence. As shown in the figure, the current flowing through one component also flows through the other. For example: small lanterns in the festival. In the series circuit, the switch is closed, both bulbs are illuminated at the same time, and both bulbs are turned off, indicating that the switches in the series circuit can control all the appliances.

2. Parallel circuit: A circuit consisting of connecting components side by side, as shown in the figure, the characteristic is that the current of the main circuit is divided into two parts at the branch, and flows through each of the two branches. For example: the connection of various electrical appliances in the home. In the parallel circuit, the switch on the trunk is closed, the switch on each branch is closed, the bulb will be illuminated, the switch on the trunk will be disconnected, the switches on each branch will be closed, and the bulb will not illuminate, indicating that the switch on the trunk can be controlled. The entire circuit, the switch on the branch can only control this branch.

3. Series circuit and parallel circuit features: In the series circuit, because there is only one path of current, the current flowing from the positive pole of the power supply will flow through the respective electrical appliances one by one, and finally return to the negative pole of the power supply. Therefore, in the series circuit, if one of the electrical appliances is damaged or disconnected somewhere, the whole circuit will become an open circuit, the circuit will have no current, and all the electrical appliances will stop working, so in the series circuit, each of them is used. The appliances are intertwined with each other, either working all or stopping all work. In a parallel circuit, the current flowing from the positive pole of the power supply is divided into two paths at the branch, and each current flows through it, therefore, even if one branch is disconnected, the other branch still forms a path with the trunk. It can be seen that in the parallel circuit, the branches are not involved.

Series voltage division, parallel shunt.

Principle: In a series circuit, the currents on the resistors are equal, and the sum of the voltages across the resistors is equal to the total voltage of the circuit. It can be seen that the voltage on each resistor is less than the total voltage of the circuit, so the series resistor is divided.

In a parallel circuit, the voltage across the resistors is equal, and the sum of the currents across the resistors is equal to the total current (the mains current). It can be seen that the current on each resistor is less than the total current (dry current), so the shunt resistor is shunted. The series and parallel connection of resistors is like water flow. There is only one road in series. The larger the resistance, the slower the flow, the more branches in parallel, the larger the current.

To determine whether the electrical devices in the circuit are connected in series or in parallel:

Series and parallel are the two most basic forms of circuit connection, and there are certain differences between them. To determine whether the components in the circuit are connected in series or in parallel, they must grasp their basic characteristics. The specific method is:

(1) Electrical connection method: Analyze the connection method of electrical appliances in the circuit, and connect them one by one in series; parallel between the two points of the circuit is parallel.

(2) Current flow method: When current flows from the positive pole of the power supply, the current flows through each component in series; when it flows through two branches at a certain point, and finally closes together, it indicates that the circuit is connected in parallel.

(3) Method of removing components: arbitrarily remove one electrical appliance and see if other electrical appliances are working normally. If all electrical appliances are removed, and other electrical appliances can continue to work, then the connection relationship of these electrical appliances Is parallel; otherwise it is in series.

(4) Replace the wire with a stroke line. You can connect all the appliances with one wire to connect them in series, but not parallel.
