A heater coil is cut into two equal parts and only one part is now used in the heater. The heat generated will now be

four times

doubled

halved

one fourth

Text Solution

Verified by Experts

The correct Answer is:

(b) `H = (V^2t)/R`
Resistance of half the coil = R/2
`:. As R reduces to half, 'H' will be doubled.
