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. Calculating the power rating of these... Read more...

It’s hard to miss the biggest coming revolution in transportation: electric vehicles. Sports cars, sedans, pickup trucks, semis, heavy equipment in agriculture and construction—even alternative transportation like electrified miniature cars, bikes, and scooters.

The reason is a bad case of gas. Not indigestion, but greenhouse gas. To keep climate change in check, CO2 e... Read more...

Feedback loops are the bread and butter of control systems. To prevent something from spiraling into larger and larger oscillations or spiked values, it’s critical to bring them back into normal ranges.

Not only is that the case for electrical circuitry, but for physical systems. Any moving device under the power of a motor of any sort typically needs a braking system to con... Read more...

In demanding design parameters, specialized components can be necessary. When the power to dissipate is at least 5 watts, that means power resistors.

All resistors dissipate energy and generate some heat. Power resistors differ in the larger amounts of energy they can burn off as heat, through a challenging application of Ohm’s law. That requires designs that will let the co... Read more...
