Power as a relational concept: Power exists in relationships. The issue here is often how much relative power a person has in comparison to one's partner. Partners in close and satisfying relationships often influence each other at different times in various arenas. Power as resource-based: Power usually represents a struggle over resources ...
The portion of instantaneous power that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as instantaneous active power, and its time average is known as active power or real power.
The power factor is defined as the ratio of real power to apparent power. As power is transferred along a transmission line, it does not consist purely of real power that can do work once transferred to the load, but rather consists of a combination of real and reactive power, called apparent power.
In international relations, power is defined in several different ways. [1] Material definitions of state power emphasize economic and military power. [2] [3] [4] Other definitions of power emphasize the ability to structure and constitute the nature of social relations between actors.
Realpolitik (/ r eɪ ˈ ɑː l p ɒ l ɪ ˌ t iː k / ray-AHL-po-lih-teek German: [ʁeˈaːlpoliˌtiːk] ⓘ; from German real 'realistic, practical, actual' and Politik 'politics') is the approach of conducting diplomatic or political policies based primarily on considerations of given circumstances and factors, rather than strictly following ideological, moral, or ethical premises.
For a simple electrical circuit running on direct current, the electrical current and voltage are constant.In that case, the real power (P, measured in watts) is the product of the current (I, measured in amperes) and the voltage from one side of the circuit to the other (V, measured in volts):
Real value takes into account inflation and the value of an asset in relation to its purchasing power. In macroeconomics, the real gross domestic product compensates for inflation so economists can exclude inflation from growth figures, and see how much an economy actually grows.
The definition of exponentiation can be extended in a natural way (preserving the multiplication rule) to define for any positive real base and any real number exponent . More involved definitions allow complex base and exponent, as well as certain types of matrices as base or exponent.
