To calculate the voltage across a capacitor, the formula is: 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. Note:Vo is the initial voltage across the capacitor, if any.
As the charge, ( Q ) is equal and constant, the voltage drop across the capacitor is determined by the value of the capacitor only as V = Q ÷ C. A small capacitance value will result in a larger voltage while a large value of capacitance will result in a smaller voltage drop.
After googling I found that the circuit can be solved by considering the capacitor as a load and finding the Voc and Rth by using Thevenin's theorem ( Or its dual Norton's theorem). Now R value in the time constant is replaced with Rth value and Vs voltage with Vth voltage. Finally the voltage across capacitor, Vc= Vth (1-exp (-t/RthC))
The voltage across a capacitor is directly related to the amount of charge it stores and its capacitance. This formula is pivotal in designing and analyzing circuits that include capacitors, such as filtering circuits, timing circuits, and energy storage systems.
Voltage drop across the two non-identical Capacitors: C1 = 470nF and C2 = 1μF. Since Kirchhoff’s voltage law applies to this and every series connected circuit, the total sum of the individual voltage drops will be equal in value to the supply voltage, VS. Then 8.16 + 3.84 = 12V.
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)
