To calculate current going through a capacitor, the formula is: All you have to know to calculate the current is C, the capacitance of the capacitor which is in unit, Farads, and the derivative of the voltage across the capacitor. The product of the two yields the current going through the capacitor.
The charge on a capacitor works with this formula: Q = C * V To compute changes in that charge (we call this the current), take the derivative dQ/dT = C * dV/dT + V * dC/dT Now proclaim the capacitance to be a constant, and that simplifies to dQ/dT = C * dV/dT = I (the current)
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.
Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open. If the voltage is changing rapidly, the current will be high and the capacitor behaves more like a short. Expressed as a formula: i = Cdv dt (8.2.5) (8.2.5) i = C d v d t Where i i is the current flowing through the capacitor, C C is the capacitance,
The capacitor current indicates the rate of charge flow in and out of the capacitor due to a voltage change, which is crucial in understanding the dynamic behavior of circuits. How does capacitance affect the capacitor current?
Finally, the individual voltages are computed from Equation 8.2.2 8.2.2, V = Q/C V = Q / C, where Q Q is the total charge and C C is the capacitance of interest. This is illustrated in the following example. Figure 8.2.11 : A simple capacitors-only series circuit. Find the voltages across the capacitors in Figure 8.2.12 .
