Network Elements and the Concept of Circuit

  1. In the circuit shown below, steady state was reached when the switch s was open. The switch was closed at t = 0. The initial value of the current through the capacitor 2C is:
    1. 0 A
    2. 1 A
    3. 2 A
    4. 3 A
Correct Option: C

At steady state switch was open & capacitor → open ⇒ at t = 0 switch is closed

I =
18
2 + 4

= 3 Amp
I =
10 - 4
-
4
= 3.1 = 2A
