I need an adjustable power resistor that can be switched with a resolution of 1Ω. After some thought and web surfing, I bought some 10W wirewounds, which are available in E24 values so that 1, 3, 12 ...

An electronic component that is used to vary the amount of current that flows through a circuit. It works by sliding a wiper terminal across a resistive material, typically a thin film or chunk of ...

This 3V to 24 volt variable-regulated power supply can be adjusted from 3 to 25 volts and is current limited to 2 amps as shown, but may be increased to 3 amps or more by selecting a smaller current ...

As our economy continues to drive the emergence of energy-efficient systems such as hybrid and electric vehicles, composite aircraft, and wind turbines, the need for power resistors has expanded.

If you need a potentiometer for a project, chances are pretty good that you’re not going to pick up a pencil and draw one. Then again, if you’re teaching someone how a variable resistor works, that ...
