AI Customer ServiceIn the next equation, we calculate the current across a capacitor. The current across a capacitor is equal to the capacitance of the capacitor multiplied by the derivative (or change) in the voltage across the capacitor. As the voltage across the capacitor increases, the current increases.
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)
The product of the two yields the current going through the capacitor. If the voltage of a capacitor is 3sin (1000t) volts and its capacitance is 20μF, then what is the current going through the capacitor? To calculate the current through a capacitor with our online calculator, see our Capacitor Current Calculator.
The current across a capacitor is equal to the capacitance of the capacitor multiplied by the derivative (or change) in the voltage across the capacitor. As the voltage across the capacitor increases, the current increases. As the voltage being built up across the capacitor decreases, the current decreases.

We get or where v(t0) = q(t0)/C is the voltage across the capacitor at time t0. Equation. (6) shows that the capacitor voltage depends on the past history of the capacitor current.
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.
