Question

If current is doubled what happens to heat produced

Answer 1

Answer:

heat will also get doubled because current flowing through the conductor is directly proportional to heat.

Answer 2

Answer:

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

So

$h \: is \: directly \: proportional \: to \: {i}^{2}$

On doubling current,

Heat becomes 4 times its original value.
