Electro Magnetic Induction And Alternating Currents Question 29

Question: L, C and R represent physical quantities inductance, capacitance and resistance respectively. The combination representing dimension of frequency is [MP PET 1995; DCE 2001]

Options:

A) LC

B) (LC)1/2

C) (LC)1/2

D) CL

Show Answer

Answer:

Correct Answer: B

Solution:

Frequency =12πLC

So the combination which represents dimension of frequency is

1LC=(LC)1/2

For series R-L-C circuit, Z=R2+(XLXC)2

=(300)2+(1000×0.91061000×2)2=500Ω
