Current Questions

let's keep this simple. Voltage is the "force" pushing electricity through the speaker.  Current is the amount of electricity that moves.  They are related by the resistance of the speaker (or whatever) to the flow.  If it has little resistance, lots of electricity will flow.  This varies by many factors in speakers, and dynamically changes with frequency etc.  Some speakers are "easy" to drive (lots of resistance, don't need to push much current)others the reverse.

Note that instantaneous current it typically more useful than continuous.  Music is nto continuous and has a peak-to-average ratio of 7-15X.

you need to watch "the story of electricity" done by, i believe channel 5 in the UK with a physics professor from U sussex. Superb and answers many fundamental questions.

And as both an engineer, and also one who's stupid enough to have spent a lot of time designing high end stuff commercially (its a terrible way to make money) -my advice is absolutely learn some basic engineering, but really dont worry about it.  In the end all this suff is a trade off of cost/size/heat.  What is important is that inefficient or lower impedance speakers, which demand lots of those current things (amps, or getting really techie, movement in electrical charge) need beefy amps.

Beware a little knowledge.  Continuosu current emands serious beef, weight, size etc. But most music is not continuous - it has a peak:average ratio of about 10X. So what one really needs is the ability to seamlessly burst. The burst is actualyl voltage, but (because I=V/R remember) if it doesnt have the current ot back up its "ask",the burst will be truncated into some pathetic shadow of its self.  Flabby at best, loss of dynamics, etc.  Distortion of one kind or another.

So given how inter-related these thigns are either learn it really really well, or dont assume you can make major inferences.

Sorry: complex.
