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
To find the equivalent total capacitance Cp C p, we first note that the voltage across each capacitor is V V, the same as that of the source, since they are connected directly to it through a conductor. (Conductors are equipotentials, and so the voltage across the capacitors is the same as that across the voltage source.)
Q (C) = total charge stored in coulombs, C. C (F) = capacitance in farads, F. Given: Q (C) = 0.002C, C (F) = 0.0001F. Capacitor voltage, V c (V) = Q (C) / C (F)
If different voltage rating capacitors have to be connected in series, take care to see that the voltage drop across each capacitor is less than its voltage rating. Polarity should be maintained in the case of polarised capacitors. Series combination of capacitors is shown in the figure below
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.
Such combination of capacitors is very essential. There are two methods of combination of capacitors Capacitors are connected in parallel combination to achieve a higher capacitance than what is available in one unit. Conditions for parallel grouping Voltage rating of capacitors should be higher than the supply voltage Vs.
