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?

Question

Philoid · Accepted Answer

{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

A
