Question

Calculate the time taken for 40kC to pass through a component when a current of 5.0A goes through it

Answer 1

$Q=40kC=40\times10^3\space C$

$I=5A$

By definition of electric charge,

$Q=I\times time\\\Rightarrow time=\dfrac{Q}{I}\\\Rightarrow time=\dfrac{40\times10^3}{5}=8\times10^3\space s$
