The Current Through a Capacitor. When you start charging a capacitor, the current flows freely without any resistance in the very beginning. As the capacitor charges, the resistance increases so that less and less current can flow. When the capacitor is fully charged no more current flows through it:
About Photovoltaic Energy StorageHow to Calculate the Current Through a Capacitor. 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.
