What Is The Value Of Incidence L For Which The Physics Question

What is the value of incidence L for which the current is maximum in a series LCR circuit with C = 10 µF and ? = 1000 s⁻¹?

Options

(a) 1 mH
(b) cannot be calculated unless R is known
(c) 10 mH
(d) 100 mH

Correct Answer:

100 mH

Explanation:

Condition for which the current is max. in series LCR circuit is,
= 1 / √LC
1000 = 1 / √[ L(10 x 10⁻⁶) ]
⇒ = L = 100 mH
