Thus in a deliberative body such as Congress, the faction able to assemble a majority bloc of votes is the faction in power. Putting three aircraft carriers into the North Arabian Sea is an example of the projection of military power.
In physics, power is the rate of work done per unit time. Power can be expressed in Watts
In electricity, power is the product of voltage and current. This is also expressed in Watts.
In mathematics, a power of a number is the result of exponentiation - multiplying a number by itself a specified number of times.
