Answer to Question #260916 in Electric Circuits for Idoro

Question

A current of 3 A flows through a resistor for 6 minutes. Determine the power dissipated in the resistor if 3V existed across the resistor.

Answer 1

Power

$P=i^2R$

$R=\frac{V}{I}=\frac{3}{3}=1A$

$P=3^2\times1=9W$

Work(W)=$Pt=9\times 360=3240J$
