taiyang,

Wow, if all xkcd comics could have transcripts like this one, my uninformed ass might actually get half the jokes. :D

newIdentity,

Check out explain xkcd then

deliverator05,

I’m sorry but the symbol labelled as a wave pool is not an oscillator, it’s an AC voltage source.

AgnosticMammal,

Isn’t AC an oscillated DC?

rynzcycle,

I love that the transcription has the correct labels for those of us who aren't sparkies.

Not sure that this transcription is useful for person with vision disabilities unfortunately, would need some description of the symbols I think

TWeaK,

That is a cool diode.

xuxebiko,

This is hilarious.

Contortion,

I'm getting the urge to listen to Metallica

omgarm,

It’s been a while since I had electronics in Uni but this seems accurate.

Chadus_Maximus,

Don’t worry, someone will eventually come and tell you that it isn’t.

I could resist the urge… But… Uh… The transcript incorrectly labels the symbol for capacitor, it’s actually the NEMA symbol for a contactor. Had to make sure I wasn’t sobbing my foot in my mouth. Capacitor symbol is extremely similar, but the right side needs to be bent like a parentheses foot it to be a capacitor like -|(-
