Answer 2

$\red{SOLUTION:-}$

As we know,

H = I²Rt

It can also be written as

H = I²× $\frac{V}{I}$ × t

H = I×V×t

H= P×t (Power = V×I)

________________________

Given:-

Power = 12W

Time = 1min = 60s

______________________

Using the formula, we get

H = 12×60

H = 720J

______________________

Hence, heat produced is

$\boxed{\huge{720J}}$
