In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

The heart of this digital volume controller DVC circuit is IC2 4067, 16-channel analog multiplexer. Because the 1kΩ has been connected between every input and output, the multiplexer can act like a ...

The function of this automatic volume control circuit is to amplify signals without distorting its dynamic compression. The amplitude differences in the signal are levelled off and the disturbing ...

The diagram above is a typical PCB layout in Altium Circuitmaker software. The days of “electro” and “mechanical” being separate disciplines are long gone. Virtually all mechanical systems now come ...

The scientists are going to show us how electrical energy flows around an electrical circuit. Title: Circuit symbols This is what a battery looks like as a circuit symbol. Electricity can travel ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!
