Text Solution

Verified by Experts

At constant temperature, the strength of the current (I) in a conductor is directly proportional to the potential difference (V) between it's ends.
`:. I prop V implies I = (V)/(R ) implies V =IR` (mathematical form)
where R is comstant, it is called the resistance of the conductor.
