----------------------------------------
In an alternating current source the emf of the source is changing Periodically (sinosudaly) and hence the current is also varying.
Let the source emf is given by
where V is the instantaneous Voltage (potential difference), Vm is the maximum voltage and is the angular frequency corresponding to which the changes are taking place ( = 2/T, T is time period).
If the circuit contains only resistance R, the instantaneous current in the circuit is given by
here Im is the maximum ...
