1) A capacitor consists of two metal surfaces separated by an electrical insulator with noelectrically conductive path through it. Why does a current flow in a resistor-capacitorcircuit when the switch is closed?
2) If a 100 ? resistor is placed across a 0.10 μF charged capacitor which is initially charged to 3 V, how long does it take it to discharge to 2 V? To 1 V?
3) How does the initial value of the current in an RC circuit depend upon the (a)resistance? (b) capacitance?
