power
(pou’ər)

The source of energy used to operate a machine or other system.

The rate at which work is done, or energy expended, per unit time. Power is usually measured in watts (especially for electrical power) or horsepower (especially for mechanical power). For a path conducting electrical current, such as a component in an electric circuit, P = VI, where P is the power dissipated along the path, V is the voltage across the path, and I is the current through the path. Compare energy, work.

Mathematics The number of times a number or expression is multiplied by itself, as shown by an exponent. Thus ten to the sixth power, or 106, equals one million.

A number that represents the magnification of an optical instrument, such as a microscope or telescope. A 500-power microscope can magnify an image to 500 times its original size.

power definition

In physics, the amount of energy put out or produced in a given amount of time. Power is often measured in watts or kilowatts.

In mathematics, a power is a number multiplied by itself the number of times signified by an exponent placed to the right and above it. Thus, 32, which means 3 × 3, is a power — the second power of three, or three squared, or nine. The expression 106, or ten to the sixth power, means 10 × 10 × 10 × 10 × 10 × 10, or one million.
