In a house having 220 V line
A variable capacitor is adjusted to its lowest capacitance C0 and is connected with a source of constant voltage V for a long time. The resistance of connecting wires is R. At t=0, its capacitance starts to increase so that a constant current I starts to flow through the circuit. Calculate at time t, (i) Power supplied by the source (ii) thermal power generated in the connecting wire (iii) rate of increase of electrostatic energy stored in capacitor (iv) What do you infer from the above three results?
