In the Fig. shown, all elements used are ideal. For time t<0, S₁ remained closed and S₂ open. At t=0, S₁ is opened and S₂ is closed.If the voltage V_C2 across the capacitor C₂ at t = 0 is zero, the voltage across the capacitor combiation at t = 0⁺ will be

The current through the $$2\,\,k\Omega $$ resistance in the circuit shown in Fig. is

The equivalent capacitance of the input loop of the circuit shown in below

For the circuit shown, find out the current flowing through the $$2\Omega $$ resistance. Also identify the changes to be made to double the current through the $$2\Omega $$ resistance.
