What is the value of inductance L for which the current is maximum in a series LCR circuit with `C = 10 muF and omega = 1000 s^(-1)` ?

A

1 mH

B

Cannot be calculated unless R is known

C

100 mH

D

10 mH.

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) : At resonance condition of LCR circuit current is maximum .
`omega^(2)= (1)/(LC)`
`L= (1)/(omega^(2)C)= (1)/((1000)^(2)xx10xx10^(-6))=(1)/(10)H`
`L = 100 mH`
