Difference Between Power and Electricity

Key Differences

Power is a measure of the rate at which energy is transferred or converted per unit of time, commonly used to describe how much work an electrical device can perform. Whereas, electricity specifically refers to the flow of electrons through a conductor, which is the physical phenomenon that enables the use of electrical power.
Power is quantified in watts (or kilowatts), indicating the capability of electrical equipment or devices to perform work, such as lighting a bulb or running a motor. On the other hand, electricity is measured in terms of volts (electrical pressure) and amperes (current flow), which together determine how power is distributed and used in electrical systems.
In everyday usage, "power" often colloquially refers to electrical energy, highlighting its application, like power supply or power cut. Whereas electricity is more technically used to discuss aspects related to its generation, distribution, and consumption, such as electricity generation or electrical wiring.
The generation of power involves converting various forms of energy like mechanical, solar, or chemical into electrical energy. On the other hand, the generation of electricity typically involves transforming these energies directly into electrical current through generators or batteries.
Understanding the distinction is crucial in fields such as engineering and physics, where power might involve other forms of energy beyond just electrical, such as mechanical or thermal. Whereas electricity is strictly confined to the parameters of electrical charge and its behavior in different mediums.

Electricity

A property of certain of the fundamental particles of which matter is composed, called also electric charge, and being of two types, designated positive and negative; the property of electric charge on a particle or physical body creates a force field which affects other particles or bodies possessing electric charge; positive charges create a repulsive force between them, and negative charges also create a repulsive force. A positively charged body and a negatively charged body will create an attractive force between them. The unit of electrical charge is the coulomb, and the intensity of the force field at any point is measured in volts.

Electricity

Any of several phenomena associated with the accumulation or movement of electrically charged particles within material bodies, classified as static electricity and electric current. Static electricity is often observed in everyday life, when it causes certain materials to cling together; when sufficient static charge is accumulated, an electric current may pass through the air between two charged bodies, and is observed as a visible spark; when the spark passes from a human body to another object it may be felt as a mild to strong painful sensation. Electricity in the form of electric current is put to many practical uses in electrical and electronic devices. Lightning is also known to be a form of electric current passing between clouds and the ground, or between two clouds. Electric currents may produce heat, light, concussion, and often chemical changes when passed between objects or through any imperfectly conducting substance or space. Accumulation of electrical charge or generation of a voltage differnce between two parts of a complex object may be caused by any of a variety of disturbances of molecular equilibrium, whether from a chemical, physical, or mechanical, cause. Electric current in metals and most other solid coductors is carried by the movement of electrons from one part of the metal to another. In ionic solutions and in semiconductors, other types of movement of charged particles may be responsible for the observed electrical current.
