Where does one get a 100GΩ resistor?

I wasn't hijacking the thread. The original post said that the resistor was 1E+11, or 100GΩ. I would have thought that the leakage across the PCB would have been near that figure.

I once had problems finding 100MΩ resistors, but that was about 40 years ago.

 

What do you need a 100 gigaohm resistor for?

 

Maybe 10 neon bulbs (painted black) in series work as 100 G-ohms.

Make your own. The material options are not limited to the list but it is a start...

What do you need a 100 gigaohm resistor for?

That question in itself is better than any answer given so far

 

100 gigaohm is practically an open circuit.

Voltage sensing on High Voltage power supplies?

 

Voltage sensing on High Voltage power supplies?

Okay? How high of voltage? 100G on a one million volt power source would still only allow 10 microamps (.01 milliamps) through.

I predict at least 10 - 20 more posts before any real info is given if at all.

It was never a real problem - it was a rhetorical question on another thread that a mod decided was a hijack and moved to this new, non-value-added thread.

 

I once made some very high resistance bleeder resistors by painting resistive ink on the glass bulb of CRTs. You can buy resistive inks in a wide variety of resistances then adjust the dimensions of the resistors and the viscosity of the ink to obtain the desired resistance. Not nearly as easy as it might sound.

 

Well you can buy them so someone must use them!
Here is a 500kV power supply. Perhaps there is one in there.

When the mods do this they should add an explanation of what was done. They used to do this when making a move.

 

Here is the original post on the board:

The OP commented that he had a 1E+11 Ω resistor on his circuit. I was just curious as to where one would get such a diode. Reading the use, I assume that the precision is fairly high (0.5% or better), so that would rule out Q&D solutions.

My question was considered a hijacking and thus this spin-off posting.

For those of you who just skim the post, I DO NOT NEED A 100GΩ RESISTOR!

 

Then what was this about in post one?

It's a question without further explanation on which in normal conversational English carries the strong implication of you likely needing one.

Poor writing skills on your part does not imply poor reading skills on our part.

Same with a thread being a branch off of another thread. If it was not specified that it's a break off from another thread and no link is given how are we to know the proper context of the first post?

 

10 microamps (.01 milliamps) through.

Someone check my math: wouldn't 1 meg volt divided by 1 gig ohm equal 0.001 amps? (1 milliamp)

Yes, it would but if you read the title of the thread...........
