Question

A small radio receiver uses a battery that is capable of delivering a constant current of 40 mA for a period of 5.0 hours.

Calculate the total charge delivered by the battery.

Answer 1

Current Delivered by battery= 40 mA
Time =2 hours
Charge is defined as the current crossing in a second.
So
charge Q
\[Q= I \times T\]
I= current in Amperes
T= time in seconds
\[Q= 40 mA \times 5 hours\]
\[1 mA= 10^{-3} A\]
and
\[1 hour = 3600 seconds\]
I think you can do now, Can't you?@brodeh
