Question

when the current is reduced to half the heat generated will be


a)H/4 b) H/2 c)H/3 d) H


choose the correct Answer​

Answer 1

Answer:

: If the resistance of a conductor is reduced to half its initial value, then the heating effect in the conductor will become half. When current transmit through a conductor, heat energy is generated in the conductor.

Answer 2

Heat produced in the resistor: 

H=I²Rt⟹H∝R

∴  R′=R/2⟹  H′=H/2
