1. The problem statement, all variables and given/known data We used a watt-hour meter in a lab, 400 revolutions of the dial = 1kWh. We measured the time for 10 revolutions of the dial ( in seconds). How would I calculate the power? Time for 10 revs = 146s 2. Relevant equations 3. The attempt at a solution Power = (3600s/hr) / (146s) * (10/400) *1kWh = 0.62069 W ?
