Question

How much charge must be passed through a cross section area of a wire in $50sec$ for current to be $0.1A$?

• A. $50C$
• B. $500C$
• C. $5C$
• D. $20C$

Answer 1

The correct option is C $5C$

Electric current is defined as:
$I=\frac{Q}{t}$
where:
Q: Amount of electric charge passed through a cross-section area.
t: Time for which charge is flowing in the circuit.
$I=0.1A$ and $t=50s$
$⟹Q=It$
$Q=0.1\times 50$
$Q=5C$
