The following formulas and equations can be used to calculate the capacitance and related quantities of different shapes of capacitors as follow. The capacitance is the amount of charge stored in a capacitor per volt of potential between its plates. Capacitance can be calculated when charge Q & voltage V of the capacitor are known: C = Q/V
Finally, the individual voltages are computed from Equation 6.1.2.2 6.1.2.2, 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 .
C = Q/V If capacitance C and voltage V is known then the charge Q can be calculated by: Q = C V And you can calculate the voltage of the capacitor if the other two quantities (Q & C) are known: V = Q/C Where Reactance is the opposition of capacitor to Alternating current AC which depends on its frequency and is measured in Ohm like resistance.
The capacitor may be modeled as two conducting plates separated by a dielectric as shown on Figure 2. When a voltage v is applied across the plates, a charge +q accumulates on one plate and a charge –q on the other. Figure 2. Capacitor model capacitor plates i = dq . And thus we have, dt
When a designer of circuitry wants to specify a DC capacitor, he or she uses the symbol shown in Figure 14.1b. The straight side of that symbol is designated the high voltage side (the positive terminal) while the curved side is designated the low voltage side. We will use either symbol in DC situations. 2.)
Capacitance represents the efficiency of charge storage and it is measured in units of Farads (F). The presence of time in the characteristic equation of the capacitor introduces new and exciting behavior of the circuits that contain them. Note that for DC (constant in time) dv signals ( = 0 ) the capacitor acts as an open circuit (i=0).
