Consider a series circuit containing a resistor of resistance R and a capacitor of capacitance C connected to a source of EMF with negligible internal resistance. The wires are also assumed to have zero resistance. Initially, the switch is open and the capacitor discharged. (Figure 1)
1) Immediately after the switch is closed, what is the voltage across the resistor?
2) Immediately after the switch is closed, what is the direction of the current in the circuit?
In the circuit in the figure above, the emf equals 5.63 V and hasnegligible internal resistance. The capacitance equals 1.31 µF andthe resistance equals 1.82 MΩ. Switch S has been closed for a longtime. Switch S is opened. After a time interval equal to one timeconstant of the circuit has elapsed, find the following:(a) the charge on the capacitor plate on the right (in µC)(b) the rate at which the charge is increasing (in µC/s)(c) the current (in µC/s)(d) the power supplied by the battery (in µW)(e) the power delivered to the resistor (in µW)(f) the rate at which the energy stored in the capacitor isincreasing (in µW)
