 This article is about the concept of power in the social and physical sciences.
   For the use of the term in electrical contexts, see Electric power.


Power in a general sense is the ability to influence or outright control the behavior of people or the course of events. The term has extensive applications across a variety of disciplines, from physics to political science, sociology, and psychology.

Definitions and Concepts[edit]

In the context of social sciences, power is the capacity of an individual or group to influence the actions, beliefs, or conduct (behavior) of others. The element of power is inherent in the structure of societies and institutions. Power can manifest in different forms, such as coercive power, economic power, political power, and cultural power.

In physics, power is defined as the rate at which energy is transferred, used, or transformed. The scientific unit of power is the watt, which is one joule per second.

Types of Power[edit]

  • Coercive Power: This form of power is based on the ability to deliver threats or punishment to others.
  • Reward Power: This involves the ability to confer valued material rewards or create other positive incentives.
  • Legitimate Power: Often derived from a formal position or office held in a government, organization, or other group structure.
  • Expert Power: This is based on what one knows, experience, and special skills or talents.
  • Referent Power: This type of power stems from the ability to convey a sense of personal acceptance or approval.

Theories of Power[edit]

Several theories have been proposed to understand the mechanisms and dynamics of power in different contexts:

  • Pluralist Theory: Suggests power is distributed among many groups and that the balance of power is constantly shifting.
  • Elite Theory: Argues that power is concentrated in the hands of a small, distinct group which controls most of the resources.
  • Class Theory: Views power as derived from social class divisions and focuses on the dominance of one class over another.

Power in Political Science[edit]

In political science, power is often analyzed in terms of its distribution and exercise within a state or between states. The concept of sovereignty and the role of law and governance are central to understanding political power.

Power in Sociology[edit]

Sociology examines power at the macro level (e.g., the power of societal norms and values) and at the micro level (e.g., power in interpersonal relationships). The work of Max Weber and Michel Foucault are notable in the study of power in sociological theory.

Power in Psychology[edit]

In psychology, power relates to the dynamics within relationships and the impacts on personal behavior and the psyche. Theories such as the dynamics of power and control in abusive relationships or the role of power in the development of personality are key areas of study.
