This Capacitor Voltage Calculator calculates the voltage across a capacitor based on the current, I, flowing through the capacitor and the capacitance, C, of the capacitor.
As the voltage being built up across the capacitor decreases, the current decreases. In the 3rd equation on the table, we calculate the capacitance of a capacitor, according to the simple formula, C= Q/V, where C is the capacitance of the capacitor, Q is the charge across the capacitor, and V is the voltage across the capacitor.
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 formula which calculates the capacitor voltage based on these input parameters is V= 1/C∫Idt, where V is equal to the voltage across the capacitor, C is equal to the capacitance of the capacitor, and I is equal to the current flowing through the capacitor. Many times, you will see the extended formula, V= V0 + 1/C∫Idt.
All you must know to solve for the voltage across a capacitor is C, the capacitance of the capacitor which is expressed in units, farads, and the integral of the current going through the capacitor.If there is an initial voltage across the capacitor, then this would be added to the resultant value obtained after the integral operation.
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)
