Ans.2 Three elements : Battery, Generator and Breaker
Battery: A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
working: When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free electrons difference is delivered to the external circuit as electrical energy.
Generator : it’s a device that receives mechanical energy and converts it to electrical energy. Generator simply forces the motion of the existing electrical charges in the wire of its windings by using the external mechanical power. The charges pass through an external electrical circuit before being transformed to electricity.
working: Electric generators work on the principle of electromagnetic induction. A conductor coil is rotated rapidly between the poles of a horseshoe type magnet. The conductor coil along with its core is known as an armature.
Breaker: A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overcurrent/overload or short circuit. Its basic function is to interrupt current flow after protective relays detect a fault.
working: The circuit breaker is opened by applying pressure to the trigger. When there is a faulty current flowing through any part of the system, the trip coil of the breaker gets energized thereby moving away from each other, thus opening the circuit.
Ans 3. Current, I = 10 A ( total load from a battery in Amp. )
Ans 4. P = V*I
An Ammetrer is a device which measures the amount of current flowing in a circuit.it is very low resistance device.if it is connected in parallel it would draw most of the current and get damaged hence it is connected in series.
