Chapter 26, Problem 3PA
You are an electrician working in an industrial plant. A 30-hp three-phase induction motor has a current draw of 36 amperes at full load. The motor is connected to a 480-volt line. A three-phase wattmeter indicates a true power of 22 kW. Determine the power factor of the motor and the amount of capacitance needed to correct the power factor to

In AM, 50% modulation indicates that 33.3%.11.1%). of the total transmitted power is in the sidebands (0%,50% 2. To obtain coherent detection in AM receiver, an extra signal is added to the modulated signal, this signal called (PLL, IF carrier, pilot carrier, subcarrier). 3.
