Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...

Pickering Interfaces has announced a new family of PXI and PXIe programmable resistor modules, its first that can handle up to 2A and 200V (or as limited by max power). Credit: Pickering Interface ...

Moving the position of the slider on this resistor, changes the length of wire in the circuit which changes the resistance. A variable resistor is used in some dimmer switches and volume controls. As ...
