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 rarr oo`, the equivalent 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

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