Power vs. Electricity: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on December 1, 2023
Power refers to the rate of doing work or transferring energy, while electricity is a form of energy resulting from charged particles like electrons.

Key Differences

Power, in a general sense, refers to the rate at which energy is transferred or converted. In contrast, electricity specifically denotes the presence and flow of electric charge, typically via electrons, used for energy.
Power is measured in watts, indicating how quickly energy is used or transferred. Electricity, however, is not measured in watts but can be measured in terms of voltage (volts), current (amperes), and resistance (ohms).
Power is a broader term in physics, encompassing various forms of energy like mechanical, electrical, and thermal. Electricity is a specific type of energy, associated with electrical devices and power generation.
In practical applications, power describes how fast an appliance can convert electricity (or other forms of energy) into useful work, like a light bulb converting electrical energy into light. Electricity is what flows through power lines and cables, powering those appliances.
Power can be generated from various sources, including electricity, but also from mechanical, thermal, or chemical sources. Electricity itself is a form of energy that can be generated from various means, such as hydro, solar, or nuclear power.
