Question

A current of 5 mA flows through a circuit for 10 seconds. How much charge will flow through it?

Answer 1

• Current=I=5mA
• Time=t=10s
• Charge=Q=?

We know

$\boxed{\sf I=\dfrac{Q}{t}}$

$\\ \sf\longmapsto Q=It$

$\\ \sf\longmapsto Q=(5\times 10^{-3})10$

$\\ \sf\longmapsto Q=50\times 10^{-3}C$

$\\ \sf\longmapsto Q=50mC$
