Question

a current of 2.0A flows through a light bulb. what is the amount of charge flowing through the light bulb in 40000ms?

Answer 1

• Current=I=2A
• Time=t=40000 ms=400s
• charge=Q=?

We know

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

$\\ \sf\longmapsto Q=It$

$\\ \sf\longmapsto Q=400\times 2$

$\\ \sf\longmapsto Q=800C$
