Network theory miscellaneous
  1. S is open, V0 = 6 V, i = 0. S is closed at t = 0, the values of i and at t = 0+ are given by—


    1. 0, 6
    2. 2, 0
    3. 1, 3
    4. 0, 3
Correct Option: D

V = L
di
dt


6 = 2
di
dt

or
di
= 3
dt

when the switch is closed at t = 0+ there will be only transient current.
i.e. i L (0+)=0
