∙ 6y ago
An electronic measuring device also known as a multimeter is used to check the electrical voltage in homes and industrial areas. The checks that need to be done before a multimeter is used is the to plug the black test lead into the black socket marked com. The red lead plugs into the red socket marked voltage and resistance.

What measures electrical resistance?
an ohm meter OR multimeter is used to measure the electrical resistance...
What you measure voltage into?
You measure voltage using a voltmeter which involves measuring the electrical potential difference between 2 points in an electrical circuit.
Where do you set the dial when you are measuring resistance on house current?
YOU DO NOT "measure resistance on house current".You never measure resistance of anything that has any path to any source ofpower ... not to a wall outlet, a battery, a windmill, a solar panel, etc. You onlymeasure resistance when all power is REMOVED from the circuit or componentyou're measuring. Then, the range you choose for the ohmmeter depends onthe component or circuit you're measuring, NOT on how it's powered when it'sturned on.
What is the use of resistance box?
The use of a resistance box or a "Decade Box" is to help calibrate instruments used to measure electrical values such as Voltage, Current, and Resistance. Without them you would not have a known value of resistance to use as a set point.
What is CT burden in electrical engineering?
CT (current transformer) Burden is the maximum load that the CT secondary can drive (e.g. meters or protection relays) Why do you care about burden when ordering current transformers? The burden is the termination impedance of the measuring instrument. The measuring instrument can be an analog or digital energy meter, a data logger or a recorder. All instruments that use a current transformer to measure line current must terminate the CT with a resistance (impedance in same case which means there is some inductance involved). A CT supplier should be given the burden when ordering. Technically, the total burden for a CT is the internal winding resistance, the connecting lead resistance and the measuring instrument input resistance. Some Ct's are installed a long distance from the measuring instrument and the connecting leads can have a resistance as much as 0.002 ohms per foot (both ways because the current makes a complete round trip). This resistance will cause an error if not taken into account.
What checks should be done to an electrical measuring device before attempting to measure electrical resistance?
Some of the checks that can be done to an electrical device before checking electrical resistance include the proximity of other magnetic fields and other electrical circuits. Measure electrical resistance while at a safe distance from strong electrical circuits.

What electrical measuring instrument is used to measure polarity index test?
A low resistance ohmmeter is used
What is an absorption dynamometer?
An absorption dynamometer is an instrument used to measure force, by measuring the energy absorbed via friction or electrical resistance.
What are ohms?
the unit of measure for electrical resistance
What is avo meter?
avometer comes from " avo " and "meter". 'A' means amperes, to measure electrical currents. 'V' means the voltage, to measure voltage. 'O' means ohms, to measure ohms or resistance. finally the meter or unit of measure. often reffered to as AVO meter multimeter or multitester. AVO meter is a device for measuring voltage, current, both AC and DC and electrical resistance.
How do you measure armature resistance practically?
by using measuring meter
What device is used to measure the resistance of a resistor?
You can use a multi-meter to measure resistance. The specific portion of the meter for measuring resistance is called an ohmmeter.
What is the ohm unit used to measure?
Ohms measure electrical resistance. The resistance in ohms is the voltage divided by the current.
What is the difference between digital and mercury thermometer?
Digital thermometers measure electrical resistance and Mercury thermometers measure thermal expansion.
Is a measure of resistant to electricity?
The Ohm is the unit of electrical resistance.
The number of ohms in a circuit is a measure of the?
The electrical resistance of the circuit
