Question

If $20$ coulomb charge is flowing in $0.5$ second from a point in an electric circuit when the value of electric current in amperes will be

• A. $10$
• B. $40$
• C. $0.005$
• D. $0.05$

Answer 1

Answer: (B)

$40$

The current is defined as rate of flow of charged particles.

i.e.

$i=\frac{Q}{t}$

$Q=20C$

$t=0.5s$

Hence, $i=\frac{20}{0.5}=40A$
