Find current through the battery
(a) just after the switch is closed
(b) long after the switch has been closed

Text Solution

Verified by Experts

Just after closing the swich, inductor offer infinite resistance
`I=(18)/(9)=2A`
(b) After long time, inductor offers zero resistance
`I=(18)/(9//3)=6A`
