Electrostatic and Capacitance The electric field intensity at a point situated 4 meters from a point charge is 200 N/C. If the distance is reduced to 2 meters, the field intensity will be 1200 N/C 2000 N/C 800 N/C 1600 N/C 1200 N/C 2000 N/C 800 N/C 1600 N/C 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 VR > VC VC > VR VR = VC VR and VC = 0 VR > VC VC > VR VR = VC ANSWER DOWNLOAD EXAMIANS APP
