A 
, F capacitor, a 0.10 H inductor and a 
resistor are connected in series with an a.c. source of emf 
.
Find (i) the frequency of the emf,
(ii) the reactance of the circuit,
(iii) the impedance of the circuit,
(iv) the current in the circuit and
(v) the phase angle. Also find the effective voltages across the capacitor, inductor and resistor.
Text Solution
Verified by ExpertsCHECK THE SOLUTION.
Sol. (i) The given emf is 
.
Comparing it with 
, we have
(ii) The inductive reactance is
The capacitive reactance is
∴ net reactance of the circuit is
Since 
,the net reactance is capacitive.
(iii) The impedance of the circuit is
(iv) The current in the circuit is
Here 
(v) The phase angle 
is given by
The effective (rms) voltages across the capacitor, inductor and resistor are
