Detailed Solution

If the potential difference across a conductor is halved, the current gets halved.
Ohm’s Law states that the current

(I)

flowing through a conductor is directly proportional to the potential difference

(V)

applied across its ends, provided the temperature and other physical conditions remain unchanged.

V \propto I

It can be expressed mathematically as

V = IR

; where

V

is the potential difference,

I

is the current and

R

is the resistance.
