Question

State Ohm's Law.Draw A Graph between voltage and current for a mettalic conductor.Draw a circuit diagram which consists of battery,ammeter, voltmeter,resistor,rheostat and a key.

Answer 1

The current passing through the metallic wire is directly proportional to the current flowing through it provided its temperature remains the same.....This is known as Ohm's law.

Answer 2

Ohms law states that the current flowing through a conductor is directly proportional to the potential difference applied across it's end provided that the physical and the temperature of the conductor remain the same.
