What is a power resistor? Power resistors are used to dissipate energy by converting it to heat. They are designed to maintain stable performance under heavy loads and to handle thermal conditions safely. Power resistors are usually physically larger than other resistors, and are designed for higher loads—typically over one watt.

A power resistor is a resistor designed and manufactured to dissipate large amounts of power in a compact physical package. This section will discuss several types of power resistors and their construction. The following table provides an overview of …

These resistors handle a huge amount of power in high-powered systems which range from the continuous flow of current to a direct power surge. So this article discusses an overview of a power resistor – working & its applications.

Resistor power rating is an important parameter to consider when choosing a resistor for a particular application. The job of a resistor is to resist current flow through a circuit and it does this by dissipating the unwanted power as heat.
