how we can measure the ohm of resistance
Answers
Answer:
Here are the steps for measuring resistance in the simple circuit:
Remove the battery. ...
Turn the meter selector dial to one of the resistance settings. ...
If you're using an analog meter, calibrate it. ...
Touch the meter leads to the two points in the circuit for which you wish to measure resistance.
Explanation:
Resistance is the measure of electrical “friction” as electrons move through a conductor. It is measured in the unit of the “Ohm,” that unit symbolized by the capital Greek letter omega (Ω). Set your multimeter to the highest resistance range available. ... When you do, the meter should register 0 ohms of resistance.
Answer:
most ohmmeters work by passing a (usually small) current through the sample and measuring the voltage drop - thus finding the resistance by Ohm's law V=IR. Any internal resistance of the ohmmeter should be well known and included in the calculation (usually automatically).
