You must learn to think about conductive surfaces differently. At 8 GHz the chassis or external ground connection, between enclosure...

I suspect your problem is more of a wave guide problem than capacitance. With a 3cm wavelength, your "ground" level will criss-cross the...

You are right. It is 12KV. In a classroom environment, I would still keep the voltage at or below 50V.

The area of you capacitor is about 0.53 square meters. The minimum non-zero distance is 0.1mm. That works out to about 4.7pF. So, with...

Here are the "concepts of concern". A thin coating of water will not readily flow, so you are looking for either a very thin coat that...

And you want to keep track of how many PF'ers are following your link? I am guessing you are referencing this article. It opened for me...

Another strategy for dealing with leaks is to recover the leaking fluid and pump it back into the system. For your Helium system, I...

Just saying hello and look forward to sharing knowledge and ideas on the forum!

For contrast, in the simplest kind of room thermometer: There is a small resistor in the thermostat that mimics the heating of the room...

Especially in contrast to Hydrogen, Helium is very inert - it is the most inert element. It's two electrons exactly fill the 1s2 shell...

I search on "helium permeation rates by temperature". It looks like about anything will allow Helium permeation and at 350C, and the...

Hello Ellan: Try this (Romanian to English) Hello everyone, I'm Ellan, from Romania. I'm interested in classical electromagnetism and...

As a Software Engineer whose been at it for more than half a century, if you want to work out what's going on, both attacks are...
