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 amount of heat produced from an electric heater is \(J/s\).
