ALL YOU NEED TO KNOW ABOUT AMMETER

Our life is incomplete without electricity. Whatever we do, be it watching television, working on laptop, using tube lights for light, using microwaves, charging batteries for our cars or vehicles, all of these need electricity. At the end of the month, we get an electricity bill which we need to pay. We need to pay for the amount of electricity we have used. How do we measure the amount of electricity used by us? We use ammeter for this purpose.

PRINCIPLES OF ELECTRICAL RESISTANCE

An electron that travels through wires of the external circuit witnesses resistance. Resistance is termed as the hindrance to the flow of electric charge. The electron does not travel from one terminal to another in a linear direct route. Instead, it follows a zig-zag path resulting from countless collisions with fixed atoms inside the conducting material.
