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.
When a voltage difference (potential difference) is applied across a component or system, it refers to the capacity of that component or system to store an electric charge. The ratio of the magnitude of the charge (Q) held on one of the plates to the potential difference (V) between the plates is known as a capacitor’s capacitance (C):
Thus, you see in the equationt that V C is V IN - V IN times the exponential function to the power of time and the RC constant. Basically, the more time that elapses the greater the value of the e function and, thus, the more voltage that builds across the capacitor.
The following formula can be used to estimate the energy held by a capacitor: U= 1/2CV2= QV/2 Where, U= energy stored in capacitor C= capacitance of capacitor V= potential difference of capacitor According to this equation, the energy held by a capacitor is proportional to both its capacitance and the voltage’s square.
The various results obtained in respect of a series combination of capacitors can be summarized as below: (i) All the capacitors connected in series acquire equal charges. (ii) The supply voltage (V) is always equal to the sum of the potential differences established across the capacitors i.e.
But, if C is the capacitance of an equivalent single capacitor for the three given capacitors in series, acquiring the same charge of Q coulombs, when the same voltage of V volts is applied across its terminals, then Hence, from Equation (1) and Equation (2),
