Dissipated - GCSE Physics Definition

Reviewed by: Philippa Platt

Published

In the context of GCSE Physics, "dissipated" refers to the way energy is spread out and lost, usually in the form of heat, during the process of energy transfer.

When energy is transferred in a system, it doesn't always remain in a useful form; for example, when electrical energy powers a light bulb, not all of it is converted into light—some of it is lost as heat energy.

This energy that is scattered into the surroundings and can't be used to do further work is considered to be dissipated. Understanding dissipation is important when studying the efficiency of different systems and devices.
