Electrostatic and Capacitance A 4.7 MΩ resistor is in series with a 0.015 µF capacitor. The combination is across a 12 V source. How long does it take the capacitor to fully charge? 35 ms 3.5 ms 352 ms 70.5 ms 35 ms 3.5 ms 352 ms 70.5 ms 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 and VC = 0 VC > VR VR = VC VR > VC VR and VC = 0 VC > VR VR = VC VR > VC ANSWER DOWNLOAD EXAMIANS APP
