An electric heater of resistance 5

Ω

is connected to an electric source. If a current of 6 \(A\) flows through the heater, then find the amount of heat produced in 5 \(minutes\).

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

\(I\) \(=\) 6 \(A\)

\(R\) \(=\) 5

Ω

\(t\) \(=\) 5 \(minutes\)

On converting minutes to seconds, we get \(t\) \(=\) \(s\)

The formula for the amount of heat produced,

\begin{array}{l} H = i^{i} i i \\ = i^{i} \times i \times i \end{array}

Thus, the amount of heat produced from an electric heater is \(J\).
