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
The calculation of the self-capacitance of single-layer coils in the program Coil64 is based on the Dr. David W Knight essay without considering the influence of the coil-former. It is understood that the inductor operates at a frequency much lower than the self-resonance frequency and it is an air core coil.
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.
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. Capacitive reactance is calculated using: Where
The capacitance C C of a capacitor is defined as the ratio of the maximum charge Q Q that can be stored in a capacitor to the applied voltage V V across its plates. In other words, capacitance is the largest amount of charge per volt that can be stored on the device: C = Q V (8.2.1) (8.2.1) C = Q V
Reactance is the opposition of capacitor to Alternating current AC which depends on its frequency and is measured in Ohm like resistance. Capacitive reactance is calculated using: Where Q factor or Quality factor is the efficiency of the capacitor in terms of energy losses & it is given by: QF = XC/ESR Where
