Heat dissipated by resistor

WebAny resistor in a circuit that has a voltage drop across it dissipates electrical power. This electrical power is converted into heat energy hence all resistors have a power rating. … WebPower dissipation in a resistor: When current is going through a resistor, the electrical energy is lost as heat. All that heat need to go somewhere. Power dissipation of a resistor is its ability to lose heat to the surrounding without overheating and burning up.
