It's like a pipe, but the water stays still?

[c9]

I do not get electricity. Luckily, that's not a prerequisite for purchasing and using it. Otherwise I would be in trouble. Can anybody help me with this?

I have a new laptop, with an AC adapter as listed below. I also have a spare AC adapter from another computer (but the same company), with slightly different specs. The connector is the same, so it's physically possible to plug in either one. What I want to know is, is it OK for me to plug in either one? I've been told by someone smarter than me that I should not. Just wondering why.

Neat, can you point me to anything agreeing with this? I haven't hunted extensively, but everything I've seen says I should avoid it...

ummm, i don't have any definitive sources on that, other than me.... i think i've given you this info before, but just in case...

think in terms of a water pipe...
voltage = pressure of the water
amperage = amount of water flowing

if you're really concerned, you could cut into the cable, and find a 3.34amp fuse (likely a 3.5 is the closest you'll find), and put that in line with one of the wires... that way, if the computer ever starts using more than the 3.5 amps that the power supply is capable of providing, the fuse will blow.

I'm definitely not curious enough to start cutting and splicing. :) Just wondering if there's a longer writeup anywhere. I'll have to keep hunting.

My OAC physics teacher told it as a river and waterfall, amps = amount of water flowing, volts = height of the waterfall. Similar ideas I suppose.

I'm inclined to agree with you on being able to use the cord.
