Can average power be negative
Web• Average power is the product of voltage (rms magnitude), current (rms magnitude) and power factor, where power factor is the cosine of the angle between voltage and current. EXAMPLE 5.1 A trace from an oscilloscope is shown in figure 5.5. The voltage channel was set on 5 V/cm, while the current channel was set on 100 mA/cm. Determine the power WebJan 9, 2024 · The average electric vehicle requires 30 kilowatt-hours to travel 100 miles — the same amount of electricity an average American home uses each day to run ...
