220 volt +/- 10% isn’t really a good design standard. As it doesn’t live up to the requirements within the EU to start with.

I’m cynical that the non-tetany behaviour of AC results in being able to pull away. Remember that mains is oscillating at >50 x a second, so the pull-away would have to be within that cycle, as well as overwhelming the hyperpolarisation and ignoring the fact that normal neuromuscular signals are essentially pulse-frequency modulated with saturation causing desensitivity (I.e. A continuous signal is ignored)

I think this could have failed purely due to the inadequate heat sink, made worse by elevated summer temperatures. Add the possibility of counterfeits in, it was doomed to failure.

The only powertrain available to test was the new, higher-powered 2.0-litre hybrid, designed to offer eco-conscious buyers who like a bit more performance an alternative to the resolutely fuel- and CO2-focused 1.8-litre. Mated to a six-speed auto, there are two standout features: chiefly, that the link between the accelerator position, revs and actual performance are better matched than ever before, with the CVT-esque disconnect between them now greatly – if not entirely – reduced, and secondly that, so long as you are happy to let the gearbox run as an auto, rather than play with the mostly superfluous wheel-mounted paddleshifters and try to act out your inner F1 driver fantasy, there is strong, smooth performance on offer.

*My* electricity is cheap (~$0.065/kW), so that 117 miles would cost about $7.61. Gas in my area is down to about $2.70/gallon, so the total fuel cost for those 253 miles would be about $16. Other areas of the country might be higher for electricity and lower for gas.

You can also see the top of the mechanism for the tilt / swivel LCD panel, peeking out on either side of the electronic viewfinder. The viewfinder itself projects quite a bit from the rear of the camera, a decision that was apparently necessitated by the tight packaging of components in front, including the AF module, popup flash, hot shoe, and microphones.

Yes you can use those high voltage safely, BUT your typical DIY people don’t even bother to read or understand datasheets. These people need the proper training, but aren’t likely to be bother to go beyond the typical monkey see monkey do watching youtube and think they know it all. I have seen enough of bad layouts of the average projects that doesn’t even understand that the creepage space between the primary and secondary side of an optoisolator aren’t meant to be for routing!

But this time, as I tested the 2018 Kia Niro PHEV, everything went right. I was able to drive and charge this plug-in hybrid like a normal person who has to keep it for more than a week. Full charges greeted me each morning. And, at the end of my test, some seriously impressive fuel economy blew my mind.

A path is the key. To be thrown across a room and to be banged up, ie bashing into a wall, must have been a low current high voltage event that made a path!

The microwave I recently tore apart had a hefty resistor connecting the capacitor to ground, to quickly drain it of power when the magnetron itself wasn’t energized. (The capacitor itself had a label saying there should be a resistor bridging the cap’s contacts for the same purpose.)

MLVs come in various chip form sizes, and are capable of dissipating significant surge energy for their size. Thus, they suit both data-line and power-supply transient-suppression applications.

In my experience, the more people know about electricity, the more cautious they are. And the more they have to deal with dangerous voltages, the more cautious they are. With few exceptions, most Youtubers you see doing dangerous stuff online have no idea what they are doing. Speak to a decent electrician and you’ll see they work more safely than most engineers and thousand time safer than amateurs. We don’t really need electrical cowboys showing off how dangerous the stuff they do is.
