23.11 Reactance, Inductive and Capacitive
Consider the capacitor connected directly to an AC voltage source as shown in Figure 23.44. The resistance of a circuit like this can be made so small that it has a negligible effect compared with the capacitor, and so we can assume negligible resistance. Voltage across the capacitor and current are graphed as functions of time in the figure.
