  1. In the circuit shown, i(t) is a unit step current. The steady-state value of v(t) is

    1. 2 V
    2. 3 V
    3. 6 V
    4. 9 V
Correct Option: A

At steady-state condition, capacitor is open and inductor is shorted, then

current through 6 Ω = 1 ×
3
=
1
Ω
3 + 63

and V(t) = L
di
+ 6i
dt

= 0 + 6 ×
