Step 1

To find the initial voltage, *V*_{C }(t = 0^{-}) and differential equation of voltage, *V*_{C} (t) across capacitor in the given circuit:

Step 2

Initially before time t = 0, the circuit position is connected at position 1.

The reduced circuit for time t < 0 can be drawn as:

Step 3

From the reduced circuit, As there is no voltage source present in the circuit, the voltage acro...
