Question

1. The current through a conductor is made four times its initial value. Calculate how will it affect the heat produced in the conductor?

Answer 1

Answer:

the heat produced increases by 16 times

Explanation:

H = i²Rt. (i)

i' = 4i .....(ii)

H' = i'²Rt

=> H' = (4i)²Rt. from (ii)

=> H' = 16i²Rt

=> H' = 16H. from (i)
