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 ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...

With the trend toward miniaturization, temperature effects in power electronics are more pronounced than ever. If you’re dealing with temperature fluctuations in your circuit, you may need a ...
