By applying a voltage to a capacitor and measuring the charge on the plates, the ratio of the charge Q to the voltage V will give the capacitance value of the capacitor and is therefore given as: C = Q/V this equation can also be re-arranged to give the familiar formula for the quantity of charge on the plates as: Q = C x V
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 capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage 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
These calculations are included in the free Espresso Engineering Workbook. Total capacitance of series-connected capacitors is equal to the reciprocal of the sum of the reciprocals of the individual capacitances. Keep units constant.
