Parallel....series....

Old age brain cramp set in...what's the difference?
Thanks for the education

What comes to mind without looking it up:

Parallel - Running in the same direction.

In series - One right after another.

What are you doing, Doug?

Series think "in line" like flashlight batteries in a flashlight, voltage adds the total of the individual. Neg to pos.................neg to pos...........neg to pos........

Parallel, "side by side" you could parallel 2, 20, or 200 million D cells and the output voltage will still be 1.5V nominal.........neg to neg...........pos to pos

Jumpering a vehicle battery is parallel.......more amps, same voltage

This is how an electrician friend explained it to me decades ago...just one of those things that goes away...Thanks...

Nothing in particular Del. Was just reading a thread on here where you are working with someone who popped a link. Read your posts numerous times trying to remember but...well...the hamster just couldn't spin the wheel fast enough.

Since you're discussing parallel and in series, what would be better when hooking up a pair of speakers on say the left channel and a pair on the right channel?

This depends on the impedance of both the amp output and the speakers,

If you have say, two 4 ohm speakers, and an amp with 8 ohm output, you want them in series

If however reversed, IE the amp is 4 ohm output and the speakers are 8 each, put them in parallel will make the impedance half. This is different than voltage.

If you don't know, try them either way. It might be say, if the speakers are poorly matched, that using all 4 hurts the end result rather than two

Also on speakers polarity is important, because they combination can produce interferance waves and deteriorate the sound. "In general" you want all positives matched on all channels.

Speakers cables should also be the same length...
