Question

A current of $0.25A$ is flowing through a filament of an electric bulb for $20min$. Find the amount of electric charge that flows through the circuit.

Answer 1

A current $\left(i\right)$ is flowing through the filament of an electric bulb for time $t=20min$If a net charge $Q$, flows across any cross-section of a conductor in time $t$, then the current $i$, through the cross-section is, $i=\frac{Q}{t}$$Q=i\times t=0.25\times 20\times 60=300C$
