8.2: Capacitance and Capacitors
The fundamental current-voltage relationship of a capacitor is not the same as that of resistors. Capacitors do not so much resist current; it is more productive to think in terms of them reacting to it.
15.2 Simple AC Circuits – University Physics Volume 2
For capacitors, we find that when a sinusoidal voltage is applied to a capacitor, the voltage follows the current by one-fourth of a cycle. Since a capacitor can stop current when fully charged, it limits current and offers another form of ac resistance, called capacitive reactance, which has units of ohms.

Application of start and run capacitor for single phase motor. Why we applied a capacitor for single phase induction motor?The reason is to improve performance of motor by generate the rotating field sign for this motor have a two ( 2 ) stator winding,and one of it is the auxiliary and is connected by a suitable […]
15.3: Simple AC Circuits
The current through a capacitor leads the voltage across a capacitor by (pi/2) rad, or a quarter of a cycle. The corresponding phasor diagram is shown in Figure (PageIndex{5}). Here, the relationship between (i_C(t)) and (v_C(t)) is represented by having their phasors rotate at the same angular frequency, with the current phasor ...
21.6: DC Circuits Containing Resistors and Capacitors
RC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge. Figure shows a simple (RC) circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from …

Electric Fields and Capacitance | Capacitors | Electronics Textbook
A capacitor''s ability to store energy as a function of voltage (potential difference between the two leads) results in a tendency to try to maintain voltage at a constant level. In other words, capacitors tend to resist changes in voltage. When the voltage across a capacitor is increased or decreased, the capacitor "resists" the change by ...
