In the circuit shown in the figure, what is the value of `I_(1)` just after pressing the key K?

A

5/7 A

B

5/11 A

C

`1 A`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
Just after pressing the key K, the inductor offers infinite resisstance. So, net resistance will be 14`Omega`.
`therefore" "I=V//R=5//7A`
