Why isn't resistance constant?
If measuring resistance of materials or resistors by themselves(not soldered into a circuit board) resistance is constant. If measuring resistance of a circuit then it could fluctuate with the components functioning in the circuit.
When measuring resistance with an ohmmeter?
Yes.
The standard unit of eletrical resistance is?
The standard measuring unit for resistance is ohm.
When measuring resistance where does the red cord go?
For simple resistance measurements it usually doesn't matter.
Anderson Bridge for measuring inductance and resistance?
yes.it is used to find self-inductance and internal resistance
Why could the total resistance of the circuit vary when measuring resistance using a multimeter?
Residence of one component varies overtime and from component to component.
What is ohmmeter?
An ohmmeter is a type of electrical metre that measures electrical resistance. When in resistance-measuring mode, multimeters also operate as ohmmeters. An ohmmeter measures the resistance of a circuit or component by passing electricity through it.
What happed if ammeter is placed in parallel with the component?
Ammeters have a very low resistance, as to not interfere with the circuit they are measuring current in. As such if you connect a very low resistance in parallel, the component is essentially shorted. A great many ammeter fuses have been blown because of this.
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.

Unit for measuring resistance?
" Ohm "
When measuring resistance with an ohmmeter?
Yes.
What is the unit for measuring electric resistance?
ohms.Ohm is the measurement of resistance. Ω
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.
The standard unit of eletrical resistance is?
The standard measuring unit for resistance is ohm.
Measuring instrument for resistance?
OHM-meter.
What was the applications of galvanometer?
It can be used to form ammeter measuring the current intensity , Voltmeter measuring the potential difference , ohmmeter measuring the resistance.
