If it were less than a number of Megohms it would not be insulation.

Why watt density too high mega ohm is low?
ohm's measure resistance, the more ohm's the more resistance the less voltage
How do you measure electrical insulation resistance value?
By Megger testing (meggering) of the motor any one can measure the IR of the motor. MEGGER is a device used to measure IR. Analog Megger device may generate 500 volts..it gives coil to coil or coil to body IR value...it should not be less than 2 Mega ohm, generally it should be or kept more than 5 mega ohm...thanks ...DEEPAK RAJPUT
1 mega ohm?
1 mega ohm=______________ ohm?
What is a mega ohm meter?
I think you mean megohm-meter or "megger" which is a high voltage, low current electrical insulation tester.
What should be minimum insulation resistance value for 11 kV HT cable?
65 meg ohm if it is 11 kv
Why watt density too high mega ohm is low?

What do megger measure?
Megger is usually short for Mega Ohm Meter. It measures high values of resistance with good accuracy. Most often used to test insulation.
How many ohms is a low resistance?
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.
Why Megger have two ranges ohm and mega ohm?
If you measure a small resistance with the megger set in Mega ohm range you get a very tiny and inaccurate result, and If you measure a huge resistance with the megger set to mega ohm range it will bottom out. To get the most accurate measurements you want what you're measuring to be about the same as the scale you're using.
When 10 ohm resistance and 100 mega ohm resistance are connected in series then what will be their conbined resistance?
The net effective resistance of resistors in series is the sum of the individuals.Combined resistance = (100,000,000) + (10) = 100,000,010Ωhms.
What is the formula used to determine insulation resistance in a motor?
2 meg ohms, 2,000,000 ohms to ground. 1 meg ohms.

What is the name of a law of resistance?
The name given to the law of resistance is Ohm's Law.
What is an electrical OHM?
A measurement of electrical resistance. It is dimensionally equivalent to Volts / Amperes. (Voltage / Current)AnswerAn ohm is the unit of measurement of resistance. Resistance is not affected by either voltage or current, but by the length, cross-sectional area, and resistivity of the conductor.
Whose name is given to the unit of resistance in an electrical circuit?
Ohm. After Georg Simon Ohm
How do you compute for voltage if current and resistance is given?
Voltage = Current * Resistance (Ohm's law)
