For instance: A microphone rated at 150 ohms to 300 ohms is considered low impedance. About 600 to 2 000 ohms is medium impedance, and 10 000 ohms or more is high impedance.
Relative to 500 ohms 5000 ohms is a high impedance. It is ten times higher.
The real impedance is the resistance in ohms more 20%. A coil resistance of 6,7 ohms X 1.20 = an impedance of 8.04 ohms. If the voice-coil had exactly 8 ohms, the impedance would be 9.6 ohms and the sound would be unclear, tending to more basses.
The difference in between Ohms and Ohms CT is that in Ohms CT it has CT at the end.
10 mega ohms.
For instance: A microphone rated at 150 ohms to 300 ohms is considered low impedance. About 600 to 2 000 ohms is medium impedance, and 10 000 ohms or more is high impedance.
There is no precise definition, but for instance: A microphone rated at 150 ohms to 300 ohms is considered low impedance. About 600 to 2 000 ohms is medium impedance, and 10 000 ohms or more is high impedance.
Usually is the input impedance of the load 10 times higher than the input impedance of the sender. So the sender's ohms is one tenth of the load.
50 in parallel with 100 ohms. Dza10 answer: Rin = 50^2 /100

Ohms is a measure of impedance (resistance), not volume.
The real impedance is the resistance in ohms more 20%. A coil resistance of 6,7 ohms X 1.20 = an impedance of 8.04 ohms. If the voice-coil had exactly 8 ohms, the impedance would be 9.6 ohms and the sound would be unclear, tending to more basses.
That is possibly the input impedance of a loudspeaker - not an impedance of an amplifier.
You can use your so called "4 to 8 Ohm's output" amplifier for your 10 ohms loudspeaker. All amplifiers have an output impedance of less than 0.5 ohms. You use impedance bridging when you connect the 10 ohm's loudspeaker. The "4 to 8 Ohm's output" means only that a 4 to 8 ohm loudspeaker will be adequate and not that the output impedance is 4 to 8 ohms! Scroll down to related links and look at "Impedance bridging - Wikipedia".
The nominal 8 inch speaker impedance can be 4 ohms, 8 ohms or 16 ohms. It depends on the make of the loudspeaker not on the 8 inches.
The VOM has the higher loading effect, because it has a lower impedance. It is typical for a VOM to have an impedance of 20K ohms per volt while the DMM has a fixed impedance of 10M ohms or 20M ohms.
