Electrostatic and Capacitance A capacitor and a resistor are connected in series to a sine wave generator. The frequency is set so that the capacitive reactance is equal to the resistance and, thus, an equal amount of voltage appears across each component. If the frequency is increased VC > VR VR and VC = 0 VR = VC VR > VC VC > VR VR and VC = 0 VR = VC VR > VC ANSWER DOWNLOAD EXAMIANS APP
