Question:
An inductance of $2.0 \mathrm{H}$, a capacitance of $18 \mu \mathrm{F}$ and a resistance of $10 \mathrm{k} \Omega$ are connected to an Ac source of $20 \mathrm{~V}$ 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?
Solution:
