SUMMARY
The power output calculated from the watt-hour meter measurement is approximately 0.6164 kW. This is derived from the formula: (1 kWh)/(400 revs) * (10 revs/146 s) * 3600 s/h. The discussion clarifies that the unit kWh represents energy, which is the product of power (kW) and time (hours), confirming the conversion of kW to kJ. The correct interpretation of the time for 10 revolutions is crucial for accurate calculations.
