Electro Magnetic Induction And Alternating Currents Question 200

Question: In given RC circuit, capacitance of capacitor C1=3μF and C2=1μF . It is given that time constant of circuit between A and B is 3 millisecond. Value of R will be

Options:

A) 1,Ω

B) 10,Ω

C) 100,Ω

D) 1000,Ω

Show Answer

Answer:

Correct Answer: D

Solution:

  • Equivalent circuit can be drawn as below RC=3×103sec

    R×3×10,6=3×10,3

    R=10000,Ω
