Hint: This question is based on the concept of power. Power can be defined as the rate at which work is done per unit time. Power is a wide concept that has its practical applications in almost every field of industry from electrical to automotive.
Complete step by step answer:
Since power is always proportional to the amount of work done, if an individual works at different rates at different times, his power will also vary. This is where the average-power concept comes into play.
We may describe power as the rate at which work is completed, or the amount of work completed in a given amount of time. Watt or joules per second is the SI unit of power.
The total energy consumed divided by the total time taken is what we call average power. In layman's terms, average power is defined as the average amount of work or energy converted per unit of time.
The formula of power is:
$P = \dfrac{W}{t}$
Here, $P$ is the power.
$W$ is the work done.
$t$ is the time taken to do the work.
So, we can confirm that the SI unit of power is joules per second ($\dfrac{j}{s}$). It is also known as Watt .
Note: Energy divided by time is the power dimension. The Watt, which is equivalent to one joule per second in the International System of Units (SI), is the unit of power. Another common and conventional metric is horsepower , which is equivalent to the power of a horse; one mechanical horsepower equals approximately 745.7 watts.
