Power dissipation occurs when electrical energy is converted into heat due to the resistance present in a circuit. When current flows through a resistor, some energy is lost as heat due to collisions between charge carriers and atoms in the material, described by Joule's law. This phenomenon is critical in electronic components, where excessive power dissipation can lead to overheating and potential failure. Proper thermal management is essential to mitigate these effects and ensure the reliability of electronic devices.

What is charge dissipation?
Dissipation is a term refereeing to any device when power is applied. All devices have a power dissipation rating which varies with ambient temperature and medium of power dissipation dispersion like a heat-sink.
Why resistor size does not varies with its value?
A: A resistor size is determined by the usage or its power dissipation. the bigger the size the more power it can dissipate due to the extra surface. SIZE is a function of power dissipation and has nothing to do with its value
