In the circuit shown there is steady state with the switch closed. The switch is opened at `t=0` Choose the correct option(s) (Given `varepsilon=24V,C_(1)=3Fand C_(2)=2F)`

Options

A. The voltage across `C_(1)` before the switch is open is 12V
B. The voltage across `C_(1)` after a long time after the switch is open is 12V
C. The voltage across `C_(2)` after a long time after the switch is open is 24V
D. The voltage across `C_(2)` before the switch is open is 8V

Answer

A, C, D

Explanation

`i=24/(3+9+6)=4/3A`
`V_(1)=4/3xx9=12`
`V_(2)=4/3xx6=8V`
at `t=infty`
`V,=V_(1)=24`
