An electric heater of resistance 5 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
\(t\) \(=\) 5 \(minutes\)
On converting minutes to seconds, we get \(t\) \(=\) \(s\)
The formula for the amount of heat produced,
Thus, the amount of heat produced from an electric heater is \(J\).
