WebbDC: Direct current; the unidirectional flow of electric charge. capacitor: An electronic component capable of storing an electric charge, especially one consisting of two conductors separated by a dielectric. differential equation: An equation involving the derivatives of a function. An RC circuit is one containing a resistor R and a capacitor C. WebbAs 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. Previous Capacitors in Parallel Next Capacitance in AC Circuits
