Question

what happens to the heat generated in a resistor when the current passing through it is doubled?​

Answer 1

Answer:

Amount of current passing through a conductor is doubled. How many times will the heat be produced? Heat produced, H ∝ I2 . So, when current is doubled the heat produced will be four times.

Answer 2

we know that,

$h = {i}^{2} rt$

therefore if r is doubled h will also be doubled.

Why?

H is directly proportional to I the current, r the resistance and t the time.
