In the given (Fig.) all the symbols have their usual meanings. At `t = 0`, key `K` is closed. Now answer the following questions.

At `t = 0`, the euivalent resistance between `A` and `B` is

A

`R_(1) + R_(2) + R_(3)`

B

`R_(1) + R_(2)`

C

`R_(1) + R_(3)`

D

indeterminate

Text Solution

Verified by Experts

The correct Answer is:
B

At `t = 0`, capacitor will behave like a short circuit and the inductor as open circuit but as `t rarr oo`, the nature is just opposite.
