Question

state the relationship b/w the electric current,the charge moving through a conductor and the time of flow. calculate the charge passing through an electric bulb in 30 minutes if the value of current is 300mA.

Answer 1

I=Q/t

Here given,
t=30min=30×60=1800sec
I=300mA
Q=It
=300×10^-3×1800
=540000×10^-3
=540C
