## What is Power:

Power, from Latin *powerful *(‘power’, ‘strength’) has various uses and meanings in different fields such as **Physical**the **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 7^{2 }. 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 ‘**c****ability 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.
