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 ...

6.1.2: Capacitance and Capacitors

The current through a capacitor is equal to the capacitance times the rate of change of the capacitor voltage with respect to time (i.e., its slope). That is, the value of the voltage is not important, but rather how quickly the voltage is changing. Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open.

4.7: Capacitors and Dielectrics

The amount of charge (Q) a capacitor can store depends on two major factors—the voltage applied and the capacitor''s physical characteristics, such as its size. A system composed of two identical, parallel conducting plates separated by a distance, as in Figure (PageIndex{2}), is called a parallel plate capacitor. It is easy to see the ...

3.1: Resistors and Capacitors

Resistors. Resistors are two-terminal passive linear devices characterized by their resistance R [ohms]: [ mathrm{v}=mathrm{iR}] where v(t) and i(t) are the associated voltage and current. That is, one volt across a one-ohm resistor induces a one-ampere current through it; this defines the ohm.. The resistor illustrated in Figure 3.1.1 is …
