Understanding Power Dissipation
In electronic components, power dissipation is the process by which energy is converted into heat. For a resistive component, this is calculated by multiplying the voltage drop across it by the current flowing through it. This calculation is crucial for selecting components with an appropriate power rating to prevent them from overheating and failing.
Formula: Power (P) = Voltage Drop (V) × Current (I)
