Meaning of Power

What is Power:

Power, from Latin powerful (‘power’, ‘strength’) has various uses and meanings in different fields such as Physicalthe Math and the Philosophy. In a generic way it is ability either possibility to do or create something. A power is also a person, entity, state, or nation that possesses great influence, force, or power.

Power in Physics

In Physical,power is the amount of worked (force or energy applied to a body) in a time unit. It is expressed with the symbol ‘P‘ and is usually measured in watts either watts (W) and which is equal to 1 joule per second. A formula to calculate power is P = T / t, where ‘T’ equals ‘work’ (in joules) and ‘t’ equals ‘time’ (in seconds).

electrical power

The power electrical is the amount of Energy emitted or absorbed by a body in a time unit. The measurement of the electrical power consumption of a domestic electrical device in kilowatt hour (kWh).

The reactive power is a type of electric power that appears in installations of alternating current, associated with the generation of magnetic fields and dissipated by reactive charges (coils and capacitors). It is represented by the letter ‘Q’ and the unit of measurement that is usually used is the reactive volt-ampere (VAr).

mechanical power

The mechanical power is the amount of force applied to a body in relation to the velocity with which it is applied One of the formulas to find it is: P = F · v . Therefore, the force (F) expressed in newtons (N) is multiplied by the speed (v) expressed in meters per second (m/s).

Power in Mathematics

A power is a Mathematic expression which indicates the multiplication of a number by itself as many times as its exponent. A power is represented as a small number written to the right and above accompanying a number (base).

A example of power is 72 . The number ‘7’ is the base and the ‘2’ is the exponent (also called index Or simply, power). This power would be equivalent to the multiplication 7 x 7.

Power in Philosophy

The concept of ‘power‘ is one of the objects of study of the Philosophy. The aristotelian philosophy defines this term as the ‘cability to be‘ in the future, as opposed to the concept of ‘act’.

In Philosophy there is also talk of power of the soul to refer to a faculty or capacity of the soul. According to some positions, three soul powers (memory, understanding and will) that allow the human being to remember, know and want, respectively.
