When the switch is closed, the initial current through the `1Omega` resistor is `A. `2A`B. `4A`C. `3A`D. `6`

Answer» Correct Answer - 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
