Four-Lead Measurement of Resistance

چکیده
The ohmmeter works well for large resistances (greater than a few 10s of ohms) and when it is possible for the probes to make good connections to the object. If the resistance is very small, it is difficult to make a good connection, or both, it is necessary to use a more complicated method to properly measure the resistance. The main problem in these two cases is that the resistance in the probes and connections becomes comparable to, or larger than, the resistance being measured.
