Q2.The following circuit has R = 10kΩ, C = 10μF . The input voltage is a sinusoid at 50Hz with an
rms value of 10V. Under ideal conditions, the current is from the source is
Answer : Option DExplaination / Solution: No Explaination.
Q6.In the figure 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 Vc2 across the capacitor C2 at t = 0 is zero,
the voltage across the capacitor combination at t=0+ will be
