In the figure shown the key is shorted at time i=0. The initial and the final currents through the battery are:

A

`1/15A, 1/10A`

B

`1/10 A, 1/15 A`

C

`2/15A, 1/10 A`

D

`1/10A, 2/15A`

Text Solution

Verified by Experts

The correct Answer is:
A
Initial current = `2/(10+20) = 1/15 A`
Final current `=2/20 = 1/10 A`
