content: Sounds like it was written by a pre-pre-Alpha version of ChatGPT...They certainly like to repeat that "1.5 times the power rating" BS...Then there's the next page about inductors!

content: Oh dear: all my vacuum-tube electronics operates well above 3 V applied to resistors of various types.(Back in the 1970s, when A-B carbon composition resistors were popular, it was normal to apply 300 or 500 V across high-resistance 2 W resistors.)I went to the trouble of sending the company an e-mail demanding where they got the absurd article about resistor voltages.

content: Quote from: Kim Christensen on June 15, 2024, 06:41:00 pmEven more ridiculous than their mis-information on resistor voltage ratings.I like the statement: "AC or DC current can flow through an inductor, but not simultaneously."Makes me wonder how I ever managed to get any of my switching PSU designs to work.

If you interpret AC as meaning the non-DC component of a waveform its false. But we abuse the notation horrendously all the time, since we talk of AC voltages...

content: And from the "Difference Between Resistor and Capacitor" article:-"Resistors are essentially switches that turn currents on or off.""...adding resistors in series increases resistance, while adding capacitors in series increases capacitance."
