Listen An AC voltage represented by e= 170 sin377t volts is applied to a resistor resulting in a current represented by i= 5.88sin377t mA. The average power consumed by the resistor is: O a) 500 mW Ob) 1 mW cer

A single phase AC motor draws 4.5 A from 220 V electricity. Three various power of the motor from the mains is 720 W. a) Calculation of the power factor of the engine. b) Calculating the Capacitance (C) and Power of the capacitor required to make the power coefficient of the motor 0,95

The circuits in Figure 4 show the expected behaviour of the RC circuit. When the waveform voltage level is high, the capacitor charges through R1. When the waveform voltage is low, the capacitor discharges through resistor R1. It is important to note that the switches in Figure 4 do not exist inside the instrument. They are an analogy to the circuit behaviour. 6. Calculate the T for this circuit: 11 GND C1 100μF C1 100μF
