Electrostatic and Capacitance If a third equal and similar charge is placed between two equal and similar charges, then this third charge will be in unstable equilibrium move out of the field of influence of the two charges remain in stable equilibrium not be in equilibrium be in unstable equilibrium move out of the field of influence of the two charges remain in stable equilibrium not be in equilibrium 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 VC > VR VR = VC VR and VC = 0 VR > VC VC > VR VR = VC VR and VC = 0 VR > VC ANSWER DOWNLOAD EXAMIANS APP
