is equivalent to a pure resistance. (E5C12) '''The coordinate system that is often used to display the resistive, inductive, and/or capacitive reactance components of an impedance is rectangular coordinates.''' (E5C13) The coordinate system that is often used to display the phase angle of a circuit containing resistance, inductive and/or capacitive reactance is polar coordinates. (E5C14)
(1) and (2) are standard capacitor circuit symbols. (3) is an example of capacitors symbols in action in a voltage regulator circuit. The symbol with the curved line (#2 in the photo above) indicates that the capacitor is polarized, meaning itâs probably an electrolytic capacitor. Maximum voltage-Each capacitor is rated for a maximum voltage that can be dropped across it. 2  Some capacitors might be rated for 1.5V, others might be rated for 100V. 3  Exceeding the maximum voltage will usually result in destroying the capacitor. 4  Leakage current-Capacitors arenât perfect.
