Examples

Subsequent designs of ohmmeter provided a small battery to apply a voltage to a resistance via a galvanometer to measure the current through the resistance. Source: Internet

A more accurate type of ohmmeter has an electronic circuit that passes a constant current (I) through the resistance, and another circuit that measures the voltage (V) across the resistance. Source: Internet

It remains correct at the centre of the scale only, which is why such ohmmeter designs always quote the accuracy "at centre scale only". Source: Internet

This type of ohmmeter suffers two inherent disadvantages. Source: Internet

To reduce this effect, a precision ohmmeter has four terminals, called Kelvin contacts. Source: Internet
