Question 490: 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
