While it might seem counterintuitive on the surface, there are a number of cases where dumping a large amount of energy into a resistor simply to turn it into heat is necessary to the operation of a ...

This project is made out of few junkbox parts and builds a useful constant current load for switch mode power supply, battery testing, and other applications. A dummy load is traditionally a big ...

This dummy-load circuit has been in use at Maxim for more than 10 years (see the figure). It's useful for testing power supplies and power amplifiers as well as drivers for LEDs, relays, and solenoids ...

At the NAB show next month, Altronic Research will show its Model 6606/12, a convection-cooled resistor load. The OmegaLine Models 6606 and 6612 are terminators for 50-ohm coaxial transmission line ...

There are so many applications for power resistors that they cannot be easily tabulated. Discussed here are a few practical, useful applications that you will find interesting. First an image with ...
