An ohm is a measure of resistance to electrical currant. Resistance relates to audio in many ways, like determining how many speakers/monitors you could wire in parallel without risking damage to your amplifier, getting the most power out of your amplifier (as power amplifiers can produce more power into lower impedance loads), or sending a high impedance signal (such as a guitar signal) down a snake to the mixer (a DI box is needed to convert the high impedance signal to one of lower impedance so that high frequency information in the signal is not degraded by the long cable run.
The link below will provide you with more information on the subject. Note that the article refers to "impedance" which is the term used for resistance in AC circuits but still measured in Ohms.

What is the difference between Ohms and Ohms CT in impedance of an audio transformer?
The difference in between Ohms and Ohms CT is that in Ohms CT it has CT at the end.
How do you calculate 1.67 ohms?
ohms law.
What is the total resistance of a 6-ohm resistor and a 12-ohm resistor in a parallel series?
In series like so ---6 ohms ---- 12 ohms --- , the total resistance is just 6 ohms + 12 ohms.assuming you mean in parallel like this:_|---6 ohms-----|-|~|-_|---12 ohms---|then the resistance of this can be calculated like so:1/6 ohms + 1/12 ohms = 1/R (where R is the resistance of the circuit as a whole)2/12 ohms + 1/12 ohms = 1/R3/12 ohms = 1/R1/4 ohms = 1/Rso R = 4 ohmsA few notes, if the resistors are in parallel the total resistance will always be less than or equal to the lowest resistance in parallel (i.e 6 ohms in parallel with 12 ohms will have resistance less than 6 ohms).Also if two resistances in parallel are the same, then the resistance is half of the resistance of both resistors (i.e. 1/2 ohms + 1/2 ohms = 1/R; 1 = 1/R, R=1 ohm which is half of 2 ohms).This process can be extended to 2 or more resistors in parallel.i.e if we had a 6 ohm, 6 ohm and 12 ohm resistor in parallel we could go1/6 ohms + 1/6 ohms + 1/12 ohms = 1/R(1/6 ohms + 1/6 ohms) + 1/12 ohms = 1/R1/3 ohms + 1/12 ohms = 1/R4/12ohms + 1/12 ohms = 1/R5/12 ohms = 1/Rso R = 12/5 ohms or 2.4 ohms
Does 17200 ohms equal 17.2K ohms?
yes.
What is 47 kilo ohms in mega ohms?
The answer is .047Megohms. 1kilo ohm is 1,000 ohms. 1mega ohm is 1,000,000 ohms. Just move the decimal over to convert.
What is the difference between Ohms and Ohms CT in impedance of an audio transformer?
The difference in between Ohms and Ohms CT is that in Ohms CT it has CT at the end.
If an amplifier has an output of 350 watts rms 8 ohms what is the output at 4 ohms?
There is no amplifier with an output impedance of 8 ohms or 4 ohms on the market. All audio amplifiers really have an output impedance of less than 0.1 ohms. Scroll down to related links and look at "Amplifiers, loudspeakers and ohms"
Do the ohms on speakers have to match the ohms of the amp?
In fact there is no "8 ohm output" on an audio power amplifier and no Zout = Zin. In audio technology voltage bridging is the normal connection method where Zout < Zin. Read the link: "8 Ohm Output" and "150 Ohm Input" - What is that?
What happens if you connect 3 ohms impedance speakers to a 8 ohms impedancece amplifier?
Sorry, but there is really no amplifier on the market with 8 ohms output impedance. The output impedance of a power amplifier is always less than 0.5 ohms. We use no impedance matching. We use voltage bridging. Scroll down to related links and look at "Interconnection of two audio units - Power amplifier and passive loudspeaker".
Can you match a 6 ohms impedance amplifiers with 4 ohms speakers?
There is really no 3 ohms amplifier on the market with an output impedance of three ohms for power matching. You will find there 0.3 ohm or less for voltage bridging. Scroll down to related links and look at "Interconnection of two audio units - Power amplifier and passive loudspeaker".
What is the Difference between 4 ohm to 8 ohm output?
There is really no amplifier on the market which has an output impedance of 4 ohms or 8 ohms. The impedance of an amplifier is always less than 0.5 ohms. We do not use matching, we use bridging when we connect the amplifier to the loudspeaker. Scroll down to related links and look at "Interconnection of two audio units".
How do you reduce the ohms from 4 ohm to 2 ohm ON A 1000 WATT KICKER AMP MONO BLOCK IM RUNNING 2-15 AUDIO PIPE SUBS IN A SEALED BOX. THIS QUESTION IS FOR CAR AUDIO?
put 2 speakers in series
Can a 900 watt 2 ohms amp power two 350 nominal subs in parallel?
Your amplifier has no 2 ohms output impedance. The output impedance will be smaller than 0.5 ohms. Put your subs in parallel. In audio we only use amplifier and loudpeaker bridging. Don't believe the myth of matching. Scroll down to related links and look at "Impedance bridging - Wikipedia".
Are 8 ohm speakers for the home stereo and 4 ohm speakers for the car?
I am also looking for a better answer to this question. I have always known that almost all car speakers were 4 ohms, unless talking about subwoofers and/or dual coiled speakers, and that home speakers were 8 ohms. And until recently have thought this to be true. Until I looked on the back of my dads pair of Dynaudio speakers and saw that the impedence was 4 ohms. Now I am completely confused. Initially I thought it was due to the Voltage and Current that Car audio lacks and Home Audio has plenty of and then I see this!!! LOL
How to feed a dipole with a balance to unbalanced transformer?
The dipole side is always 50 ohm. The other side depends on the signal source impedance requirement, like 8 ohms for audio.
What is 3000 ohms in k ohms?
3000 ohms are 3 kiloohms.
Do multiply or divide convert kohms to ohms?
Ohms are smaller than k-ohms, so number of ohms must be a bigger number. Multiply k-ohms by 1,000 to get the same resistance in ohms.
