FIGURE 2–7: Power Use Over Time

The data in the above figure is reproduced in the following table to illustrate the calculation of energy. Since the time increment of the measurement is one minute, and since we specified a constant load over that minute, the power reading can be converted to an equivalent consumed energy reading by multiplying the power reading by 1/60 (converting the time base from minutes to hours).
