From the title, I expected a comic about meditation.

You know...like, "ohhhhmmmmmmm...."

Dangit brain, stop initally choosing the unlikeliest conclusions!

Or as my old physics teacher used to say:

what is a joule per second ?


To which the only valid reply is:

yes

Ohm, btw, is an ancient German word for uncle (the mother's brother, to be precise). That's what made me smile today.

...and, 'oom', pronounced the same way as, 'ohm', is still used as the Dutch word for uncle.

While the puns are flying, perhaps we should announce some more late arrivals at the Electricians' Ball?

Here are a few to start you off...

  • Mr. John Travoltage, with his Flash Dance
  • Mr. Sherlock Ohms
  • Ms. Meg Awatt, & her murderous husband, 'Kill' Awatt (bit of a shock to see him here )
  • Mr. Wire Terp, who's come with Sir Kitt Breaker...tiny Sir Kitt Breaker - the short Sir Kitt
  • From France, Monsieur Ham, & his father, Ham Père
  • Count Dracula the Ampire, with his bat, Erry
  • Ms. Amanda Fuse
  • Mr & Mrs Dwattbulb, & their son, Andrew, and his friend Boy George, who's AC or DC
  • That bright spark Ronnie Corbett - the short Ronnie Corbett - he's a bit of a live wire. Don't pile on the agony.
  • The Ode family - Ann, Cath & Di, who are going to sing some current numbers
  • Look at the electricians out there. They're on their way to Heathrow...the sparks are certainly flying tonight! The film on the plane is 'The First Of The Fuse'
  • Mr & Mrs Trickalfault, & their son, Alec, arriving in their Voltswagon
  • There's Maurice tucking in there...he's known to us as 'Diner' Mo, and he's ever-ready

I'm sorry, I haven't a clue what I'm talking about. 8)

I was just about to write that! For more useless German terms for your relatives:
Oheim, which is another form of Ohm.
Muhme, who's your mother's sister.
Vetter, your male cousin.
Base, your female cousin (your cousine, if you like).
Why the French terms (Onkel, Tante, Cousin, Cousine) took over is anyone's guess.
I'll leave figuring out the pronunciation up to you.

As I was reading your post, I was wondering if it was just a coincidence. As I got to the end, I realised it wasn't. So as Samantha goes off for some truly shocking activities with a Polish electrician and the over-charged electron of time contacts the positive plate of doom, the time has come for me to bid you GOODBYE!!

Hmm. I need more practice I think.

This joke would have been SO MUCH BETTER if he had just swapped the last two terms:

Remember: with great power comes great resistance times current squared.

First, it just reads much better. "Comes great current squared..." is hopelessly awkward, and doesn't sound like anything anyone would say.

Second, it keeps you on the wrong track for longer.

"With great power..."
yes, tell me more...
"...comes great resistance..."
ah, yes, I see where you're going...
"...times current squared."
Wha- what?? Oh, I get it. A nerd joke.

See how much better it could be? :?

I'd just like to say that I have a test in chemical instrumentation tomorrow, and part of it involves circuits.
And this just made me happy (And might let me remember that particular formula!)

It's V = IR, but it can be placed into the formula for power, thus rendering P = IIR.

This made my day only due the the incredible amounts of entropy in the universe aligning this to be posted on the day of my exam on ohms law and simple circuits. On the question which asked for power consumption of an resistor with a found current. I smiled a little and wrote on my exam "With great power comes great current squared times resistance" ... and the answer... I just hope my professor reads XKCD...

I guess it depends on where you live. Where I live U is voltage and V is the unit for U.

Current forum edicat requires you to first say:

Randal, get out of my head.

Then give the anecdotal accounting of the event that coincides the comic to your life.

Well, you can use any letters you want: they are short-hand. Which is why I write out the formula using words for an unknown audience.

The timing of this comic is insane. We just started leaning about circuits in physics II this week.

I was in my physics studio (basically a lab) and after about 2 hours of an absurd number of calculations regarding resistors and capacitors the TAs pull this up on the projectors.

Hmm. I need more practice I think.

Brave try. It takes a special sort of dirty mind to formulate Samantha-and-her-gentleman-friend jokes. And 40-odd years of practice. And, if at all possible, Barry Cryer on your writing team. I must listen to some of the early shows again. [Mention something old and decrepit] + "Let's meet the teams"; [Preamble about something hopelessly non-musical] + "Colin Sell at the piano"; "Let's play sound charades" + [Double entendre about how gay Lionel Blair is]; "Samantha has to nip out now..." + [Ho ho - she's such a slapper]

Samantha has to nip out now, as she's meeting her new gentleman friend who's having trouble with his computer. Samantha is something of an I.T. expert, and she says she's looking forward to repairing his desktop, preventing it crashing and going down on him every couple of hours...


A dirty limerick seems to be forming, though:

    A bisexual sparky from Bicester
    Had a chaperoned date with a mister
    da da da-da-da dum
    da da da-da-da DUM

    Yet he couldn't resistor transistor

I have travelled here from the year 1969 to say this: the third and fourth lines are going to bug me for the rest of the day.

Thing is, he hasn't been careful about the brackets. You could conceivably read it as (great power) is (great current)^2 times (resistance) which is wrong unless the value of "great" happens to be 0 or 1.

One could also say that great power comes to the one who has the impulse to go the distance.
Unfortunately it dissipates with the the square of time.

I walked into one of my classes today to find this posted on the cork board. Apparently somebody really enjoyed it.

Maybe I'll search through and find a really good one to print off for my math prof. And I should probably print off the cuttlefish one for my msci prof...

I was searching for Ohm to find imformation on Georg Simon Ohm, and xkcd.com/643 was the second link Google showed me, of course I had to take a look at it. First I chortled, then I said; "WTF!" then I came here and registered, to say:

James Prescott Joule

Yes, Wikipedia does say: "Joule's first law and Ohm's law are equivalent and derivable from each other ". And Ohm was first with his law , but still I I think Mr. Joule at least deserves mention.

Love it! It's not searchable from the main web page via "current" or "resistance", though.

I'd buy a T-shirt of this one. Any chance of being able to do that?
