Question

to find the potential difference we use​

Answer 1

HLØ M@T€...

Multiply the amount of the current by the amount of resistance in the circuit. The result of the multiplication will be the potential difference, measured in volts. This formula is known as Ohm's Law, V = IR.

Answer 2

Answer:

To find the potential difference across two ends of a wire we use

V=IR

Where,

V stands for Potential Difference

I stands for Current

R stands for Resistance.

The above formula is derived from Ohm's law.

Ohm's law-

The potential difference across two ends of a wire is directly proportional to the Current applied, given that temperature remains same.
