Electrostatic and Capacitance Two plates of a parallel plate capacitor after being charged from a constant voltage source are separated apart by means of insulated handles, then the Voltage across the plates increases Charge on the capacitor increases Charge on the capacitor decreases Voltage across the plates decreases Voltage across the plates increases Charge on the capacitor increases Charge on the capacitor decreases Voltage across the plates decreases ANSWER DOWNLOAD EXAMIANS APP
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 VR = VC VC > VR VR and VC = 0 VR > VC VR = VC VC > VR VR and VC = 0 VR > VC ANSWER DOWNLOAD EXAMIANS APP
