Energy dissipation refers to the process where energy is transformed from one form to another, often resulting in a loss of usable energy. This typically occurs in systems where energy is converted into heat due to friction, resistance, or other forms of energy transfer. For example, when a car brakes, kinetic energy is dissipated as heat in the brake pads. In many physical systems, energy dissipation is an important factor to consider, as it affects efficiency and performance. Engineers often design systems, such as electrical circuits or mechanical devices, to minimize energy loss and improve overall effectiveness.
