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 ...

In various industries and applications, it’s crucial to monitor the current and frequency of devices in real-time. These ...

The easy way to measure high AC currents is to use a clamp meter but these are generally quite expensive and cost several hundred dollars at a minimum. Add-on clampmeter adaptors can work well but ...

The world of electric vehicles can sometimes seem like it comes with its own vocabulary, and that's where we come in. Look out for our ABC of EVs series, to demystify the words and phrases you'll hear ...

Have you ever wondered about the electricity that courses through your car? Do you suspect that there's a captive bolt of lightning held in a magic jar? Of course you don't. You're not a Neanderthal.

High-voltage direct current (HVDC) technology offers several advantages compared to alternating current transmission systems. For example, it allows more efficient bulk power transfer over long ...

The ever innovative and prolific Mr. Woodward has offered “PWM-programmed LM317 constant current source,” an intriguing programmable constant current source which elicited a lively conversation in its ...

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 ...

Rectifiers and ac-dc power supplies employ large bulk capacitors. During power-up, these capacitors require a large amount of current to charge up, resulting in a large inrush current. This inrush ...
