A battery is a source of electrical energy. Without batteries and eliminators, the electric circuits cannot operate. The electric current from the battery is used to power a load. The eliminator is a device that removes something.
A battery is the foundation of a direct current (DC) circuit. A circuit is the path that an electric current travels on, and a direct current describes the direction in which that happens. In a DC circuit, electricity flows only in one direction.
The battery is the power source. It supplies the required amount of electricity to the circuit. The battery supplies direct current (DC), which is constant in nature, whereas an eliminator supplies alternating current (AC), which is varying in nature.
A battery is simply a device made to stores chemical energy, which it then converts into electrical energy when in use. A battery has both the negative and positive terminals. Current flows out of the positive terminal and into the negative terminal. The current flows through an external circuit attached to the terminals, back into the battery again, producing a loop or circuit.
A battery provides an electric current by acting as a source of electrical energy. The term "battery" is used to refer to a collection of two or more connected cells; a single cell is usually referred to as a "cell". An electric battery consists of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights, smartphones, and electric cars. The negative terminal of the battery is the anode when the device is being used to supply electric power. That goes without saying that the cathode, in this case, is its positive terminal. The electrons come from the negative terminal and flows to the battery’s positive terminal via an external or peripheral electric circuit. When you connect your battery to an external load, the high-energy reactants will be converted to lower-energy products due to the redox reaction, thereby producing free-energy difference, which is then delivered in the form of electric energy to the external circuit.
What Job does a Battery do in a Circuit?
A battery has two jobs in a circuit. One is to provide constant voltage and the other is to provide a closed path for current flow.
It is a device that stores chemical energy and makes it available in the form of electrical energy. Every battery consists of at least one chemical cell. Each cell has two terminals. One connects to the cathode, the other connects to the anode. When you connect these terminals to an external circuit, electrons flow through the external circuit from the cathode to the anode, but at the same time ions flow through a solution called an electrolyte between electrodes.
A battery only stores energy, it never consumes it. The electrons that flow out of one terminal and into the other are equal in number to those flowing back in. Electrons "consumed" by devices connected to a battery are simply reinserted into it by electrolysis, so that no net loss occurs in electron current.
When the load, such as bulb is disconnected, no current flows in the circuit because there is no complete path for electrons to flow. It is the battery that functions as a pump that ensures the movement of electrons to move around the circuit.
A battery will always maintain a set voltage until it runs out of energy. That is why you can use a battery to power components or circuits that need a particular voltage. For example, if you want to light an LED (Light Emitting Diode) you need to provide 2V at 20mA of current. You can use a 9V battery and use resistors to limit the current provided as well as drop the voltage.
A battery will also provide a closed path for electrons to travel through from anode to cathode. This electron movement is called current flow. The flow of current in a battery is from the (-) negative terminal to the (+) terminal. The electrons that are flowing through the wires are negatively charged so they will be attracted to the positive (+) terminal of the battery and repelled from the negative (-) terminal of the battery and this movement causes current flow.
What does a Battery do in an Electric Circuit?
A battery is an electric circuit. It generates a voltage difference, or "electromotive force" (EMF), between its two terminals. A current flows when it is connected to another circuit. An electric circuit is a path through which electrons from a voltage or current source flow. The electrons get their way into an electric circuit through what is called the “source”, and leaves through a point referred to as the “earth ground” or “return”.
What does a Battery Eliminator Circuit Do?
A battery eliminator circuit is a type of DC power supply that does not use any batteries.
The word "eliminate" means to get rid of something, so it may seem strange to name a circuit after getting rid of something that wasn't even there. It was common, however, for some early power supplies to not use batteries. In fact, the oldest type of DC power supply, a generator, was usually used without batteries.
A typical battery eliminator circuit uses a transformer with the primary connected directly to an AC outlet and the secondary connected to a rectifier (diode bridge). The output is smoothed by a capacitor and regulated by an adjustable shunt regulator.
Here is how a typical battery eliminator circuit works:
1.AC input is fed into the transformer primary winding which transforms it into lower voltage AC in the secondary winding.
2.The output of the transformer is fed through a rectifier (diode bridge) which converts it into DC (pulsating direct current).
3.The output from the rectifier is filtered by a capacitor and then regulated by an adjustable shunt regulator (usually zener diode) which maintains a constant output regardless of load or input voltage changes.
