Therefore we can state a particularly important characteristic of capacitors: The voltage across a capacitor cannot change instantaneously. (8.2.7) (8.2.7) The voltage across a capacitor cannot change instantaneously. This observation will be key to understanding the operation of capacitors in DC circuits.
Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open. If the voltage is changing rapidly, the current will be high and the capacitor behaves more like a short. Expressed as a formula: i = Cdv dt (8.2.5) (8.2.5) i = C d v d t Where i i is the current flowing through the capacitor, C C is the capacitance,
Creating and Destroying Electric Energy...................................5-28 A capacitor is a device which stores electric charge. Capacitors vary in shape and size, but the basic configuration is two conductors carrying equal but opposite charges (Figure 5.1.1). Capacitors have many important applications in electronics.
Finally, the individual voltages are computed from Equation 8.2.2 8.2.2, V = Q/C V = Q / C, where Q Q is the total charge and C C is the capacitance of interest. This is illustrated in the following example. Figure 8.2.11 : A simple capacitors-only series circuit. Find the voltages across the capacitors in Figure 8.2.12 .
Capacitors do not so much resist current; it is more productive to think in terms of them reacting to it. 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).
Figure 5.1.1 Basic configuration of a capacitor. In the uncharged state, the charge on either one of the conductors in the capacitor is zero. During the charging process, a charge Q is moved from one conductor to the other one, giving one conductor a charge + Q , and the other one a charge − Q .
capacitor does give an illusion that a current passes through it, which could be a useful way of reasoning. A capacitor eventually blocks a DC current because the capacitor
