When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

Pulse Electronics Corporation introduces its new Sidewinder™ AC current sensors. Sidewinder products differ from traditional current sense transformers because they do not need a core. This makes them ...

Measuring AC current (220-V mains RMS current) is not as simple as measuring DC current. In DC current measurement, you can simply hook the oscilloscope probe to the shunt resistor and calculate the ...

As the story goes, the rock band AC/DC took its name from a label on an old sewing machine in the Young brothers’ home. It must have meant that the machine could run on either alternating-current or ...

For switching high-powered loads from a microcontroller, or for switching AC loads in general, most of us will reach into the ...
