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

$J$ .
