Question

The resistance of a conductor is reduced to half its initial value keeping the current constant. In doing so the heating effects in the conductor will become


A
half
loader
B
double
loader
C
one-fourth
loader
D
four times
loader

Solution

The correct option is A half
Heat produced=$$H=i^2Rt$$

Keeping $$i$$ constant  $$H\propto R$$

Hence, on reducing resistance to half, Heat produced also becomes $$half$$ of initial value.
