An $80\\,\Omega$ resistor, a $1\cdot0\text{ H}$ inductor and a $40\\,\mu\text{F}$ capacitor are connected in series to an a.c. supply of $220\text{ V}$ such that the circuit draws the maximum current. At this stage, calculate:
(a)[1.0]
Resonant frequency of the circuit.
(b)[1.0]
Capacitive reactance of the circuit.
(c)[1.0]
Impedance of the circuit
(d)[1.0]
Current flowing through the circuit.
(e)[1.0]
Phase difference between capacitive and inductive voltages.
