Question

In an electric bulb a current of $10A$ flows for $2$hrs . Find the amount of charge that has passed through the bulb.

• A. $36,000C$
• B. $720C$
• C. $72,000C$
• D. $3600C$

Answer 1

The correct option is C $72,000C$

$I=\frac{Q}{t}$, $Q=I\times t$
$=10A\times 2$hr
$=10A\times 3600s\times 2$
$=72,000c$
