    Normal resistors for High Voltage application

    The high voltage I'm trying to measure is an estimated 10kv AC from a flyback transformer. I'm using the resisters for a voltage divider so i can see what the voltage actually is. I might just buy a high voltage probe at this point lol Otherwise, I'll be using it to limit current from said high...

    Normal resistors for High Voltage application

    (Sorry for the long response time) Thanks for the ton of information, i guess the moral of the story is don't- or I'll probably just go and buy(/make?) some high voltage resisters rather than deal with all that. That leads me to another question, are liquid resisters (saltwater in an insulated...

    Normal resistors for High Voltage application

    Hi, What would happen if i used a regular resistor for voltages up to 10kv? I plan on using two of them for a high voltage probe (voltage divider) and I don't want to go out and buy/make high voltage resistors. Wouldn't the current want to flow through the wire rather than arc through the...

    Substituting a transistor for a MOSFET in a flyback driver

    Ahh, that clears up quite a bit. I don't have enough time right now to experiment with either risk, but i have taken advice from the powerlabs.org website and increased the number of turns on both the primary and feedback coils to potentially save the transistor. Since i haven't seen anybody...

    Substituting a transistor for a MOSFET in a flyback driver

    Here's the classic circuit im using: It's made to create high voltage AC from DC. I've killed a few transistors with overvoltage using this circuit and because of that im considering using a mosfet to take the higher power and maybe get better performance. Before i go out and buy a mosfet...

    Identifying circuit component (schematic)

    Thanks, I got most of that down, but what do you mean by the commons of the supply are connected? Is it single terminal or double terminal?

    Identifying circuit component (schematic)

    You can tell what I'm trying to make, but I don't know what those up-arrows resemble. I circled them in red. What do they mean?

    What's the "danger zone" for tesla coils?

    I definitely agree that I'm not ready for a real tesla coil yet, that's mainly why I'm doing extensive research on them. Right now I'm focused on that slayer exciter, hoping to make one just for fun and also knowing that it can't harm me once I eventually make it. Before I joined any forum or...

    What's the "danger zone" for tesla coils?

    AHA! I did some research and discovered it was a slayer exciter circuit, not a tesla coil. If anybody still cares: Is a slayer exciter circuit harmful at all?

    What's the "danger zone" for tesla coils?

    Man I always assumed tesla coils, at least the weak single-transistor ones were just compact transformers. Had no idea they got this dangerous And to make things clearer, I was talking about one powered by a 9v, a transistor, and a resistor. Though I didn't think that was a real tesla coil.

    What's the "danger zone" for tesla coils?

    Really? I didn't know the body wasn't able to detect it; I just assumed that the charge couldn't get through the skin. Well it still hurts like a shock to touch a plasma globe circuit, but that's some very nice information. No, I've actually made a van de graaff before. I know a lot about...

    What's the "danger zone" for tesla coils?

    Ok obviously I need some extra information about what really makes it a tesla coil. What would a plasma globe circuit be called? Because that's the only at-home example of a "tesla coil" I can think of, and it's obviously safe to touch directly (without the glass dome).

    What's the "danger zone" for tesla coils?

    First off, I know that tesla coils (at least as far as I know) operate at frequencies too high to pierce the body and go through the heart etc. But if somehow you got shocked by one with a much lower frequency, I'm asking how dangerous that would be. If 2 tesla coils had a transformer ratio of...

    How exactly does a capacitor charge?

    By "increase," I meant that the spark gaps get larger as I charge it, where I thought that the capacitor has the same amount of voltage that you charge it with regardless of how much you charge it. Thank you for clearing that up, I can die in peace 70 years from now... maybe less.

    How exactly does a capacitor charge?

    So, I have a leyden jar and I notice that while I charge it, it seems to increase with voltage as well as current (the current part is expected). I charge it using electrostatics, so maybe that's the confusion... Anyway, I didn't think that capacitors charged that way. Don't they retain the same...
