A wire cable has distributed capacitance between the conductors The stored energy in a capacitor increases with applied voltage The stored energy in a capacitor decreases with reduction in value of capacitance The leakage resistance of ceramic capacitors is generally high A wire cable has distributed capacitance between the conductors The stored energy in a capacitor increases with applied voltage The stored energy in a capacitor decreases with reduction in value of capacitance The leakage resistance of ceramic capacitors is generally high 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
