Networks Analysis and Synthesis

Q1:
The circuit in figure has reached steady values with switch open. If switch is closed at t = 0 the voltage across 2 μF capacitance at t = 0+ is

A zero

B 4 V

C 6 V

D 10 V

ANS:A - zero

At t = 0-, VC = 0 and voltage across a capacitor cannot change instantaneously.
