This thread is now on a short leash.

I doubt you can build a reliable power supply without documentation like schematics. I've also done several of this sort of design and...

I have been working with linear supplies for more than 50 years. I know what I am doing. Post your circuit diagram and I will show you...

Welcome to PF. Your Profile shows that you are in the UK, so I did a Google search on amateur rocketry clubs in the UK and got lots of...

I'll vote for the Hyatt Regency walkway collapse in KC, 1981. It killed 114 people and injured 216. Maybe not the worst disaster, but...

I have some solemn news to report. Many in the community had been wondering where the prolific @Vanadium 50 has been. V50 hasn't posted...

To drag myself back on topic, another thing I've seen in real life but don't have good photos of: This is on the north coast of Arran...

There's a sematic thing here. If you call it an input filter, most everyone will think it works at 50/60/100/120 Hz. But if it's a PFC...

Yes, true. But those inductors are big, heavy, and expensive. So you'll do well to leave them out in low power designs. If you care...

I think you're just learning why I hardly ever used those things for my breadboards. Plus, they aren't stable or durable. Basically, I...

You can choose whichever convention you like. You just have to be careful to be clear about the convention you use and be careful to...

That is correct. After the zero crossing of the applied voltage waveform (magenta), the diodes continue to conduct, the inductor current...

Because 500*0.1/50 ≠ 0.1. Your method was correct. Also, yet another example of a sloppy/bad/confusing HW question. Motors have...

Also, I'm not sure my rectified sine wave source would be an accurate model. It's a good first step, and correct if R is big. The...

The question asked "Determine how many times the amplitude of the oscillations decreases when a time equal to one oscillation period...
