Q. The heat produced by a 100 W heater in 2 min will be equal to
A) $12 \times 10^{3}\ J$
B) $10 \times 10^{3}\ J$
C) $6 \times 10^{3}\ J$
D) $3 \times 10^{3}\ J$
Explanation
(a) Heat produced by heater is given by
$H = Pt$
Given, $P = 100\ W,\ t = 2\ min = 2 \times 60s = 12s$
$\therefore H = 100 \times 120 = 12 \times 10^{3}\ J$
