The number measured by the 2000K ohm range of the multimeter is 900. Should the reading be 900K ohm or how much?

The number measured by the 2000K ohm range of the multimeter is 900. Should the reading be 900K ohm or how much?

Because it's the K gear. Of course, it reads 900K. 2000K only means its range is 2000K

380v12kw how to measure ohm with universal meter

If you divide 12000 by 380, it's about 31.6
Besides, even if you use a multimeter, you can't measure its work
The resistance measured by the multimeter is very small,
The resistance is many times smaller than when it works normally at 380 V!
Do you understand? If you don't give a score, I won't tell you why

How much current can one ohm limit

It depends on the voltage drop. If the voltage is 1V higher than the demand, I = u / r = 1 / 1 = 1a

How much current is required for a resistance of 1.8 ohm

The amount of resistance has nothing to do with the amount of current required
You should ask: resistance 1.8 ohm, voltage XXV, current? Answer: current = voltage / resistance
