Two resistors of `10 Omega` and `20 Omega` and an ideal inductor of `10 H` are connected to a `2 V` battery as shows in Fig. key `K` is inserted at time `t = 0`. The initial `(t = 0)` and final `(t rarr oo)` currents through the battery are

A

`1/15 A, 1/10 A`

B

`1/10 A, 1/15 A`

C

`2/15 A, 1/10 A`

D

`1/15 A, 2/25 A`

Text Solution

Verified by Experts

The correct Answer is:
A

at `t=0`
`I_(t=0)=2/30
=1/15 Amp`.
`at t=oo`
`I_(t=oo)=2/20=1/10 Amp`
