Overview
Power dissipation is the process by which an electrical device releases energy as heat. It is a critical factor in circuit design to prevent overheating and component failure.

Pro Tips
P = V × I (Voltage × Current).
P = I² × R (Current² × Resistance).
P = V² / R (Voltage² / Resistance).

Fun Facts
"In electronics, heat sinks are used to increase the surface area for dissipating power."
"The 'Joule Heating' effect is what makes electric heaters and incandescent bulbs work."
"Power is measured in Watts (W), where 1W = 1 Joule per second."
