Webbthe resistance. When a charged capacitor is connected to a resistor, the charge flows out of the capacitor and the rate of loss of charge on the capacitor as the charge flows through the resistor is proportional to the voltage, and thus to the total charge present. This can be expressed as : so that (1) R dq dt q C dq dt 1 RC q WebbThe experiment shows that Q ∝ V, or Q = constant × V. This constant is called the capacitance, C, of the capacitor and this is measured in farads (F). So capacitance is charge stored per volt, and. farads = coulombs volts.
