Question

State Ohm’s law.

Answer 1

According to Ohm’s law, at a constant temperature, the steady current ‘I’ flowing through a conductor is directly proportional to the potential difference ‘V’ between the two ends of the conductor.

I ∝ V . Hence, = \(\frac{1}{V}\) = constant

The value of this proportionality constant is found to \(\frac{1}{R}\)

Therefore I = (\(\frac{1}{R}\)) v

v = IR
