What is power dissipated?

The definition of power dissipation is the process by which an electronic or electrical device produces heat (energy loss or waste) as an undesirable derivative of its primary action. Such as the case with central processing units, power dissipation is a principal concern in computer architecture. Furthermore, power dissipation in resistors is considered a naturally occurring phenomenon. The fact remains that all resistors that are part of a circuit and have a voltage drop across them will dissipate electrical power. Moreover, this electrical power converts into heat energy, and therefore all resistors have a (power) rating. Also, a resistor’s power rating is a classification that parameterizes the maximum power that it can dissipate before it reaches critical failure.
