Answer:
The current through it will also decrease to half of its former value because according to Ohm's law the current flowing through a resistor is directly proportional to the potential difference applied across its ends provided that the temperature and some other necessary conditions remain constant.
This is mathematically represented as follows;
The current is thus given as
if R is constant and V is reduced to half, then we have the following;
Simplifying further we obtain
Equation (3) shows that the current I is also reduced to half.
