When an electric potential a voltage is applied across the terminals of a capacitor for example when a capacitor is connected across a battery. This variation is called the capacitors complex impedance. Lab 4 Charge And Discharge Of A Capacitor How To Find Thevenin Resistance Of A Capacitor In An Op Amp A Capacitor Is Connected In Series With A Resistor And Impedance is the total resistance in ohms of any network at a specific frequency including both the real and imaginary of angular parts. Resistance across a capacitor . Unlike a resistor an ideal capacitor does not dissipate energy. Like resistance it is measured in ohms but reactance is more complex than resistance because its value depends on the frequency f of the electrical signal passing through the capacitor as well as on the capacitance c. It is reading as if there is an open circuit across the cap...
