### Current leaks at 500 VDC

Background: I have a small soldered joint on a 500 VDC (0.1 A) lead that's exposed to air. The edges of the joint are fairly ridged and have a few significant edges. In the higher voltage range (40 kV)...

### How to reduce 30 amps to 5 [duplicate]

I recently bought a Transformer so that I can make an ionic lifter but it has a max 30 amp output and I’m sure that is way too much for what I need plus Since I have this plugged straight into the ...

### How can I rectify up to 85 kV?

I've recently gotten into eletrochemistry, and I found out that if you break through $\epsilon_{0}$ with a high enough voltage you can ionize various gasses. I've already wound a 1:1250 EE core that ...

### Why do high-voltage transformers need oil?

Someone told me that high-voltage transformers need oil because it prevents arcing. However, in terms of dielectric breakdown, isn't air the strongest? I remember from classes in college that as the ...

### Amplifying an ionization current with an op amp

My observation: Previously at my work I was assigned a project in which I needed to amplify an AC signal from a piezoelectric electric sensor. I simply made an inverted op amp circuit to accomplish ...

### Does my electric clearing field actually make ions?

I am using an electric clearing field of 15v/10cm (~150V/m) to remove ions from a test chamber, however I'm wondering to what extent the localisation of the field's reference voltage plays a role. ...
