Electro Magnetic Induction And Alternating Currents Question 178
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}} $ ?
Options:
A) 1 mH
B) cannot be calculated unless R is known
C) 10 mH
D) 100 mH
Show Answer
Answer:
Correct Answer: D
Solution:
- Condition for which the current is maximum in a series LCR circuit is, $ \omega =\frac{1}{\sqrt{LC}} $ $ 1000=\frac{1}{\sqrt{L(10\times {{10}^{-6}})}}\Rightarrow L=100,mH $
