The answer to Power Factor
A single phase electric motor has an output power of 10 kW and an efficiency of 90% at full load. The motor is fed from a 240 V supply via a cable that has a resistance of 10 milli ohms per metre length. If the terminal voltage to the motor must not fall below 90% of the supply voltage, calculate the maximum return length of the cable for a motor power factor of:
A. unity
B. 0.8 (sketch a circuit diagram and phasor diagram, the motor and line voltages are no longer in phase)
C. The power dissipated in the cable for each of the above two cases.
Understanding low, high and band pass filters, A signal in the IF section of an FM radio receiver occupies the frequency band 10.61 MHz to 10.79 MHz. Compute the bandwidth of this signal.
