just give enought current it will jump the bridge

LMAO - yur getting there ...

BTW - whats rush hour?? - I live in SE Bama, dont know how the bridge works in the big city. Ours are pretty slow, dont need to move fast for the horses & carts. ( ours dont flow real fast )

So AC would be traffic on the bridge right after the bars close and DC would be traffic on the bridge during rush hour.

A/c would be cars in both lanes going in different directions.
D/c would be a one lane drawbridge - traffic only goes in one direction.

And yes, this works for a/c or d/c.

LOL, Richard

Errr.... actually Ed, Vibrators are pulsating DC... but if you make it STOP, she GO's mad!

Swamp.... Is this you?

Have your furnace checked for traffic violations

Good question, on a sine wave it would like it is changing lanes but in reality it is changing directions.

changing lanes or direction of travel

Its like this Ed if we incorporate the whole ac dc theory into the draw bridge theory, it would come out something like this, when the draw bridge closes the cars
( electrons ) can pass to the other side. Which is fine, the difference is that if the cars are in a AC electrical circuit they will be changing lanes as they cross over the bridge ( weaving ) where as in a DC circuit they will cross the bridge in a single file line.

Hope this makes it easier.

i thought it was the circuits that was being discussed not the titles

Yes, AC stands for "alternating current"

and DC stands for " direct current"

I'm glad to see that there is a lot of talk on electricity here, I did some time in class on electrical stuff. So I may be able to help you out a little if you need it.

yes ed there is
one starts with an "A" and the other starts with a "D"

is there a diff between ac and dc circuits

But is this true with both AC and DC electrical circuits ?

Think of a switch like a draw bridge -

When the drawbridge ( switch ) is closed - cars ( electrons ) can pass - The electrons from yur meter, for instance, passes through easily with very litle resistance - remembering that yur ohmmeter is looking for resistance - so very little resistance is close to none ( or zero )

When the drawbridge is open - no cars can pass - neither can electrons though an open switch. Bcause no current can pass, using ohms law, there must be a very high resistance between the two points of the switch. The meter sees this 'open' as a very high resistance - too high for the meter to read & WaLa, the meter shows 'infinity' or 'overload'.

Hope this helps and is not too confusing,
Richard

It is good practice, and could save your life some day, to switch your multimeeter to ohms and touch the leads together to check continuity through them every time you use your meter.

If you are ever in doubt, touch your leads together and see what the meter says.

The way to think about it is that the ohm is a measurement of how hard electricity will have to travel to get across the path

For example 0 ohms would be you getting across your living room
Infinity is the same as you getting across the Atlantic with no boat

So although a “0” even though it would actually have some resistance if measured with a good meter
Would be closed
Same as a draw bridge you can’t get across it if it is open and electricity can’t get across a switch if it is open

Hope it helps and hope I didn’t insult you by over simplifying it
