An inductance of 2.0 H, a capacitance of 18 μF and a resistance of 10 kΩ are connected to an AC source of 20 V with adjustable frequency.

(a) What frequency should be chosen to maximize the current in the circuit?


(b) What is the value of this maximum current?


{a} for current to be maximum in a circuit







Where, f is frequency, is angular velocity, L is inductance of inductor, C is capacitance of capacitor, is resonance across inductor and is resonance across capacitor.


{b} maximum current (I) will be
