A zero ohm link is a piece of wire, a jumper.
Check it for continuity with an OHM meter.
0 ohms on your ohm meter indicates an open circuit; no resistance to the flow of electricity.
At 0 degrees Celsius, the resistance in the wire is 1000 Ohm.
An ohm meter across the fuse will tell you whether the link is open or closed.
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?
If you are testing with an ohm meter, it should be near 0 ohms.
Georg Ohm, see link to his biography
The " Ohm " is. 1 ohm is the resistance across which 1 volt of EMF appears when the current through it is 1 Ampere.
1 mega ohm=______________ ohm?
200 ohm
Georg Ohm first discovered his law empirically. Later he generalized it significantly and formalized it better. It seems that it got a rather cold welcome, which caused his withdrawal from the Academic world for six years. This wrong was later corrected, when he got the Copley medal. More about this is in the link about Georg Ohm. The well known law of the mathematical equation that describes the relationshipV = I * Rwas later called "Ohm's law" to remember Georg Ohm. Ohm's own idea was more another equation:Resistance R = rho * length / area.
