My goal here is to use you as a test subject. Meaning I want see what concepts you get from each of two paragraphs that follow. These relate to power and energy. Thus, I would expect you to respond with your own explanation in some fashion.
Paragraph 1.
Understanding power and energy is important. If a load is always on and constant in value, then measurement of power at any instant produces a result equal to the average power. Average power times the time duration of any desired interval produces the value of the energy used during that time interval.
Paragraph 2.
Suppose a load is on and off during a time period of interest. Assume the load when on is always the same value, and when off it is zero. In this case the average power is the "on" power value times the ratio of on time to the total time period of the on-off cycle.
