What kind of electricity is lightning?

Someone complained about a teacher using this question and the answer was disputed. After some time, the teacher claimed that the answer was that lightning is static electricity because she looked it up on the internet. So, I decided to look also, here is what I found searching for "what kind of electricity is lightning?" in google:

Electricity Facts - Dialogue for Kids (Idaho Public Television)

A couple of complaints about this site:

  • First, I am not fond of the term "Science Facts". What is a science fact? Something that is proven true? This really is not how science works.
  • Second, I am not fond of the term "electricity" either - what exactly is this?
  • The good: the site talks about the atom and talks about how Ben Franklin didn't INVENT electricity.
  • The site claims there are two kinds of electricity - static and current. I guess this ok since the definition of electricity is not too clear (to me).

Here is a table from that site:


Here they define current electricity as a steady flow of electrons. If they use this definition, then maybe lightning is static, but then what would household current be (which is AC and therefore not steady). I would define static electricity as non-moving electrons (static - doesn't that make sense). I would define current as moving electrons. In the case of lightning, it is definitely moving electrons.

Here are a couple of sites that seem to have it correct:

Another google search for "electricity lightning" gives the following:
Weather Eye - http://weathereye.kgan.com/cadet/lightning/electricity.html - "Lightning is like static electricity except on a much bigger scale". Maybe I am just being picky (probably), but here it seems they are calling "getting shocked from rubbing your feet on the floor" static electricity. If this were the definition of static electricity, then they would be correct in calling lightning static electricity on a bigger scale.

In the end, if someone asked me "what kind of lightning is electricity?", I think would focus on what is lightning and just pretend like they didn't say "electricity".

A while ago, we had a ton of lightning. As a bonus, it always happened in the middle of the night. I love sleeping where it sounds like I am on the front line in WWI - no, I don't. But, while lying awake waiting for the next BOOM I thought of something. Instead of just counting the time between…
I am totally ready to get back to blogging. In fact, I have a post that is 3/4th complete that I have been working on since before Christmas. Anyway, in order to procrastinate a little bit more I would like to share two learning observations (maybe they are not really about learning). Kids these…
This is a scanned page from a Christian science textbook published by Bob Jones University. I think they've been listening to too much Insane Clown Posse. We're all just mindless zombies here at scienceblogs, but somehow, BJU is even more brainless. I swear, a creationist could walk by right now…

considering you can measure the current of lightning, i'd say it ain't static.
