In circuit theory, voltage drops of resistive type devices are relatively simple because they do not change over time. But there are two types of devices that do create changes over time: capacitors and inductors.

In nearly every machine with motion, a selection of gears, belts, and chains sends power to the final mechanisms and power must be transmitted from the motor to the final load(s) device. Choosing between transmission methods isn’t always simple, but a few key properties can help to make the choices easier.

Whether using an industrial DIN-rail power supply or a linear supply for an audio application, these devices have the potential to fail. Although there can be several reasons, there are a few simple (and some not-so-simple) methods of testing a power supply for proper functionality.

Wiring design systems can become confusing when some switching devices send power to the load automatically while others do not. Often called ‘wet’ and ‘dry’ contacts, these devices are fairly easy to troubleshoot once the differences are understood.
