In the given circuit Fig the switch is closed at `t = 0`. Choose the correct answers.

A

Current in the inductor when the circuit reaches the steady state is `4 A`.

B

The net change in flux in the inductor is `1.5 Wb`.

C

The time constant of the circuit after closing `S` is `555.55 s`

D

The charge stored in the capacitor in steady state is `1.2 mC`.

Text Solution

Verified by Experts

The correct Answer is:
A, B
At `t lt 0, I_(L) = (6)/(6) = 1A`
At `t gt gt 0, I_(L) = (12)/(3) = 4 A`
`:. | phi| = L [i_(f) - i_(i)] = 500 xx 10^(-3) xx 3= 1.5 Wb
`:.` (a) and (b) are the corrent choices.
