  1. In fig. (a) the values i L, Vc as shown have initial values i L (0—) = 1 and Vc (0—) = 2 fig. (b) is the equivalent circuit in the s-domain. The values of V1 and V2 are—


    1. + 2 and
      2
      s
    2. - 2 and
      2
      s
    3. 2
      		and 2
      s
    4. 1 and 2
Correct Option: B

Since given iL (0–) = i L (0+) = 1
VL = L i L (0+) = 2 × 1 = 2

and Vc (0–) =
2
s

V2 =
2V
s
