What is ment by high resistance and low resistance on a meter?
On a multimeter, a high resistance would indicate a high Ohmic value and a low resistance would indicate a low Ohmic value. Specific values would be relative to device you are measuring.
Why watt density too high mega ohm is low?
ohm's measure resistance, the more ohm's the more resistance the less voltage
What kind of tests is a megger used for?
A megger is an instrument that generates a high voltage. That high voltage is then used for measuring insulation resistance, especially that of electrical devices.
How do you know if your ground wire is connected?
Measure the ground resistance from the user end point, where earth or ground cable is connected. It will show a very high resistance or open if ground is broken.
Why digital multimeter fails to read low resistance values?
They read low resistance values very well. I measured several dead shorts today accurately with a digital voltmeter. However, when attempting to measure LARGE amount of resistance, the current generator in a standard digital voltmeter may fail to effectively penetrate the medium being measured. It is for this reason that Meggers (Mega-Ohmmeters) are used to measure high amounts of resistance. They usually employ a hand crank to develop the current needed to effectively flow through the medium being measured. Sometimes digital voltmeters can be very inaccurate if they are measuring something that matches the impedance of the meter (loading effects of the voltmeter), but that is another story.
Why meter bridge can't be used to measure low resistance and high resistance?
used to measure low Resistance since it must reach a null.
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.
What is a instrument used to measure extremely high temperatures?
A thermometer
What is the definition of a fluke 117?
The Fluke 117 is a type of multimeter used for measuring electric circuits. This instrument is used by electrical profesionals to measure voltage, amparage and resistance. The Fluke 117 is a high quality instrument and is highly regarded by working professionals in the industry.

Why multimeter cannot used for measurement of insulation resistance?
Because ordinary ohmmeters are calibrated to measure a range of resistance values that are significantly lower than the resistance of insulation. It should also be realised that we usually test insulation resistance while subjecting the insulation to a high electric field, which a normal ohmmeter is incapable of producing.
Which losses are obtained form open circuit test in transformers?
This depends on the open circuit test performed and the type of transformer. In a Y/Y/D three phase transformer, the Z1N0 test losses are a measure of the high to tertiary resistance values (in the classic T model, most of this will be the tertiary resistance). Similarly the Z2N0 losses are a measure of the low to tertiary resistance.
What are the advantages of kelvin double bridge over wheatstone bridge?
1) a bridge based on the principle of Wheat stone's bridge that is used to compare two nearly equal resistances and to determine values of low resistances and the specific resistance of a wire. It differs from a meter bridge because additional resistances of similar magnitudes are included at either end of the meter wire.
What is 1 megohm?
One megohm (1 MΩ) is a unit of electrical resistance equal to one million ohms (1,000,000 Ω). It is often used in electronics and electrical engineering to measure high resistance values, such as in insulation testing or in circuits with very low current. Megohms indicate how well a material resists the flow of electric current, with higher values signifying greater resistance.
Do different materials have the same resistance?
No, different materials have different resistance values. Resistance depends on the material's electrical properties, such as its conductivity and resistivity. For example, metals generally have low resistance due to their high conductivity, while insulators have high resistance due to their low conductivity.
What is instrument potential transformer?
it is used to measure very high voltages which can not be measured with volt meter.
