I feel kinda stupid for asking this....on the topic of speakers...what are OHM's?......thanks.

Re: ok...i feel stupid but...

Very simply, ohms is the resistance against electrical current.

Re: ok...i feel stupid but...

thanks...the chris...is it an acronym for anything?

Re: ok...i feel stupid but...

You're welcome I don't think it really stands for anything to be honest. I know; strange name isn't it?

Re: ok...i feel stupid but...

Ohm isn't an acronym, it is used to honor a famous scientist by the same name.

Re: ok...i feel stupid but...

An ohm is defined as the resistance between two points on a conductor when a constant potential difference of one volt, applied between these points, produces a current of one ampere in the conductor. It is named after the German physicist, Georg Simon Ohm. cut from: http://www.linemenonline.com/classroom/ohm.html

Re: ok...i feel stupid but...

by the way, how do you pernounce ohms?

Re: ok...i feel stupid but...

Oms in English I guees.
There is law for Ohm too.
Ohms Law is a mathematical equation that shows the relationship between Voltage, Current and Resistance in an electrical circuit. It is stated as:
#

V = I x R
#

R = V / I
#

I = V / R

Where

*

V = Voltage
*

I = Current (I stands for INTENSITY)
*

R = Resistance

Re: ok...i feel stupid but...

I don't want to get too technical, but since you asked, ohms is used for both resistance and impedance. A speaker is n ohms impedance. Impedance is simply AC resistance rather than DC resistance. They're close, but not exactly the same.

If you measured the circuitry of your guitar with a simple ohmmeter, you'ld see a certain amount of resistance. Your pickup will see a different amount of resistance because the cap in the tone control blocks the DC resistance measurement, but not the AC generated by the p'up.

Its not really important to know that for most guitar wiring, but perhaps interesting.
It becomes far more relevant in power supply design.

There's a link that gives you the pernunciation on this site:

Long 'o', silent 'h.'
