Question

will there be any change in amount of heat produced if direction of current is changed give reason for your answer

Answer 1

Answer:

yes

Explanation:

becoz a/c to Henry's law of heating effect

I is directly proportional to H

Answer 2

Answer:

If direction of current reverse and it magnitude does not change,so the amount of heat produce will not change.

Explanation:

We know that

Amount of heat generated in current flowing wire in time t

Q= I²R t

Q= Heat generated

I = Current

R= Electrical resistance

t= Time

If all other quantity is same then Q ∝ I²

If direction of current reverse and it magnitude does not change,so the amount of heat produce will not change.
