When the switch is closed, the initial current through the `1Omega` resistor is
`

A

`2A`

B

`4A`

C

`3A`

D

`6`

Text Solution

Verified by Experts

The correct Answer is:
B
At `t=0` , when capacitor is under charged, equivalenresistance of capacitor `=0` in this case `6Omega` and `3Omega` are parallel (equivalent `=2Omega)`
`:. R_(n et)(1+2)Omega=3Omega`
`:. "Current from battery" =12/3 =4A`
`= "Current through" `1Omega` resistor
