Electro Magnetic Induction And Alternating Currents Question 200
Question: In given RC circuit, capacitance of capacitor $ C_{1}=3\mu F $ and $ C_{2}=1\mu F $ . It is given that time constant of circuit between A and B is 3 millisecond. Value of R will be
Options:
A) $ 1,\Omega $
B) $ 10,\Omega $
C) $ 100,\Omega $
D) $ 1000,\Omega $
Show Answer
Answer:
Correct Answer: D
Solution:
Equivalent circuit can be drawn as below $ RC=3\times {{10}^{-3}}\ \text{s} $
$ R\times 3\times {{10}^{-\,6}}=3\times {{10}^{-\,3}} $
$ R=10000\,\Omega $
