Learning Goal:
To understand the dynamics of a series R-C circuit.
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)
Let us try to understand the processes that take place after the
switch is closed. The charge of the capacitor, the current in the
circuit, and, correspondingly, the voltages across the resistor and
the capacitor will be changing. Note that at any moment in time
during the life of our circuit, Kirchhoff's loop rule holds and, indeed,
it is helpful: E-VR-Vc = 0, where VR is the voltage across the
resistor and Vc is the voltage across the capacitor.
