Question

An electric bulb draws a current of 0.25A for 20 minutes.Calculate the amount of electric charge that flows through the circuit.

Answer 1

Given:

• Current = 0.25A
• Time = 20 minutes = 20 $\times$ = 1200s

To find:

• Charge = ?

Solution:

The Formula to find the charge —

${\qquad}{\bigstar{\boxed{\sf{ I = \frac{Q}{t}}}}}$

According to the question —

$\sf \implies \: 0.25 = \frac{Q}{1200} \\ \\ \sf \implies \: Q = 0.25 \times 1200 \\ \\ \sf \implies \: Q = 300C$

Hence,the amount of electric charge is 300C.
