No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

With high enough voltage everything becomes conductive.
ELI5?
This here is the Volt family.
Marty volt is small and so he can jump across a small stream. Put up a small net and it’s impossible for him
Victor, though. He’s got some strong legs. He can jump the net and the stream.
In fact, he’s so strong he can jump over a small river but not if you put a small wall across the way. Then, even with a running jump, he’ll be blocked.
And finally there’s Kal, ahem, Clark Volt. He’s super strong. So strong it could be an ocean and with a little jaunt before leaping he’d jump it.
The stronger the volt, the further they can go and the bigger the obstacle you need to make it impossible for them to make it.
So high enough voltage can literally leap through air (that’s the arcing you see in power plants shorting or lightning) or even wood itself. Even rubber, with a high enough voltage, will be conductive since the sheer force of the current will find a path for the charge.
That’s also why we have lighting rods, it’s easier to redirect the current to a safe spot made to handle it than to try and make high skyscrapers out of a material that can resist the insane charges of lightning and still be strong enough and light enough to build with.
This answer is great! Thanks!
Lightning is just air conducting electricity. Air is not typically considered a conductor.
Everything can have a positive or negative charge. Voltage is just the difference in charge between two points. Given a big enough difference in charge any material can conduct electricity to balance the charge since nature seeks to balance out differences in charge/energy.
You can think of voltage as the force that pushes electrons through a substance. Different substances have different amounts of resistance which blocks the electrons. However with enough voltage you can overcome that resistance and push on through. Lightning for example has a very high voltage, as it travels through air which is not very conductive.
He'll, skipped that and hold the wire between two hands (don't do that, it cannot be stressed enough how much of a bad idea that is. You wanna commit die? That is by far the most efficient way of doing it, so DONT)
