This is relative to the purpose or application. 1 mega ohm may be considered "low resistance" when testing insulation levels; when testing a cable, 1 ohm may be too much. When testing substation ground grids, I believe 1 ohm is the maximum allowable value in some countries.

What is the ohm unit used to measure?
Ohms measure electrical resistance. The resistance in ohms is the voltage divided by the current.
There are three sources of resistence in a parallel circuit two of them are rated at 20 ohms the other 10 ohms what is the circuits total resistance?
The total resistance is 5 ohms. Scroll down to related links and look at "Parallel Resistance Calculator".
What is the difference between ohms and mohms?
ohms is the SI unit of resistance MHO (siemens) is the SI unit of reciprocal of resistance ie conductance
How many amps can 18volts push through 3 ohms of resistance?
A: 18volts / 3ohms = 6amps
Inductive reactance has a unit in?
Ohms, resistance in an inductor increases as the frequency of the AC signal increases, this "artificial resistance" is called impedence, and it is measured in ohms
Why the thin wire has grater resistance to electricity?
it has to do with ohms and the gauge of the wire. if you have a low ohms then you can't use a small thin wire. because the more ohms the more resistance. if you have a low omhs on a thin wire it can cause the wire to heat up. posibly catch fire.
How many Ohm resistances do you need to connect in parallel to produce a total resistance of 10 Ohm?
For an end-result of 10 ohms, you can have 1 resistance of 10 ohms, or 2 parallel resistance of 20 ohms each, or 3 resistances of 30 ohms each, etc.
What is the value for resistance 1100 ohms?
The number of ohms is, precisely, the value of the resistance.
Is ohms bigger unit to megohms?
An ohm is a unit of electrical resistance. A kilohm is 1,000 ohms resistance, while a megohm is 1,000,000 ohms resistance.
Resistance is measured in what?
Electrical resistance (and impedance) is measured in ohms(Ω).
What is the total resistance is V is 10 volts R1 is 1000 ohms and R2 is 1000 Ohms?
If they're connected in series the total resistance is 2000 ohms. If they're connected in parallel the resistance is 500 ohms.
A lenght of cirular wire as a resistance of 1 ohms if its the diameter was double its resistance woul be.?
Its resistance would be half , 0.5 ohms is the answer.
What is the Lowest ohms possible?
The lowest resistance is zero ohms.
What are ohms used for?
Ohms are used to measure electric resistance.
What has greater resistance 5ohms or 1000 ohms?
1000 ohms
What is the total resistance of 20 ohms?
Could it be.... 20 ohms(?)
What is the total resistance of a series circuit with 5ohms10 ohms 20 ohms?
35 ohms
