Question 478: AC fundamentals

Question

What is the value of inductance L for which the current is maximum in a series LCR circuit with C = 10 $\mu $F and $\omega $ = 1000 s
$-$1
?

Accepted Answer

Condition for which current is maximum in a series LCR circuit is,
$\omega  = {1 \over {\sqrt {LC} }}$
$ \Rightarrow $ 1000 = ${1 \over {\sqrt {L\left( {10 	imes {{10}^6}} ight)} }}$
$ \Rightarrow $ L = 100 mH

Answer

1 mH

Answer

cannot be calculated unless R is known

Answer

10 mH

Answer

100 mH
