Motors differ from other types of loads in one important way: The motor needs much more current to start than to run. This temporary, but significant, inrush current is what complicates motor circuit ...

Electrical engineers have been designing custom circuit boards on computers for years, but this approach simply moved the paper and pencil method to digital. It didn’t advance the craft or make it ...

There is one class of signals we have not yet covered, and that is those signals which pass within the unit from one board to another. Typically these are digital control signals or analog levels ...

Efficient processes are needed to build a circuit board. Five students in Duane Beck’s manufacturing engineering technology senior design class developed prototype equipment to improve an inspection ...

Every electronic device relies on a printed circuit board, or PCB, to connect its parts and make it work, from smartphones and laptops to simple household gadgets. However, this essential component ...

In Part 1, we looked at how to size a branch circuit and walked through a simple example. So if you’re sizing a feeder, why don’t you do it the same way? Except in cases where a feeder is also ...
