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=10μF and ω=1000s1 ?

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, ω=1LC 1000=1L(10×106)L=100,mH
