Question

A current of $0.5A$is drawn by a filament of an electric bulb for $10$ minutes. Find the amount of electric charge that flows through the circuit.

Answer 1

Step 1: Given data:-

Electric current drawn by the filament, $i=0.5A$

Time in which electric current is drawn by the filament, $T=10minutes$

Amount of electric charge flowing through the circuit, $Q=?$

Step 2: Formula used:-

$i=\frac{Q}{T}$ ………………………..(a)

Step 3: Calculation of the electric charge flowing through the circuit:-

Converting the given time from minutes to seconds, we get

$$\begin{gathered} T=10\times 60S \\ T=600s \end{gathered}$$

Substituting the given value of electric current and the value of time in seconds obtained above in equation (a), we get

$0.5A=\frac{Q}{600s}$

$Q=0.5\times 600$

$Q=300C$

Hence, the amount of electric charge flowing through the circuit is equal to $300C$
