An electric heater of resistance 8

$Ω$ draws 15 $A$ from the service mains $2\ hours$ . Calculate the rate at which heat is developed in the heater.

[Note: Enter the answer as a whole number.]

$I$

$=$ 15

$A$

$R$

$=$ 8

$Ω$

The formula for the amount of heat produced is

$\begin{array}{l} P = i^{i} i \\ = i^{i} \times i \end{array}$

Thus, the rate of generation of heat from an electric heater is

$W$

$1$
