Given 10V ac source, LCR series circuit, Imax at resonance=2 A; f= 200Hz Imax = 1.2A;
f=350Hz Imax = 1.5A

Given these parameters what is the resonant frequency and how did you get this value?

What is L and C in the series circuit?

Given these values what is the phase angle at f=250Hz?

----------------------------------------
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 ...
