Given the circuit and the input waveform, what is the charge voltage across the capacitor express answer in volts 4" 0 20 V -20 V 64 Vi C 10V + R V 19

Find equivalent inductance at the terminals a and b of the circuit below. *Round off the final answer to the nearest 4 decimal places with unit. Rounding off should only be done on final answer.

Assuming the capacitor is fully charged, what is the voltage across the capacitor 2 seconds after the switch is opened? E=33 V, R1=300 kſ, R2=300 k, C=10 uF R2 R1 ww + 55.2 V None of the above 31.5 V 47.3 V 23.6 V 39.4 V #6 C

The capacitance of a certain variable capacitor may be varied between limits of 1 × 10-20 F and 5×10-10 F by turning a knob attached to the movable plates. The capacitor is set to 5 × 10-10 F, and is charged by connecting it to a battery of EMF 200 V.  What is the charge on the plates? The battery is then disconnected and the capacitance changed to 1 × 10-10 F.  Assuming that no charge is lost from the plates, what is now the potential difference between them? How much mechanical work is done against electrical forces in changing the capacitance?
