Calculate the rms value of the waveform shown in Fig P 9.37
Answer to relevant QuestionsThe current waveform in Fig P 9.38 is flowing through a 5- resistor. Find the average power absorbed by the resistor. An industrial load consumes 100 kW at 0.8 pf lagging. If an ammeter in the transmission line indicates that the load current is 284 A rms, find the load voltage.Find the source voltage in the network shown in Fig P 9.50 A plant consumes 60 kW at a power factor of 0.5 lagging from a 220-V rms 60-Hz line. Determine the value of the capacitor which when placed in parallel with the load will change the load power factor to 0.9 lagging.A 5.1-kW household range is designed to operate on a 240-V rms sinusoidal voltage, as shown in Fig. P9.67. However, the electrician has mistakenly connected the range to 120 V rms, as shown in Fig P9.67. What is the effect ...
