Micro/Milli-Ohmmeters
| An ohmmeter is an instrument used to measure
the electrical resistance of a conductor. In normal usage, the
ohmmeter operates by using the voltmeter to measure a voltage
drop, then converting this reading into a corresponding resistance
reading through Ohm's law. If the current is known, the voltage
drop across the unknown resistance may be read to give the resistance
directly. If the current is not known, or if it is not possible
to measure the voltage across the unknown directly, reading
the voltage drop across a known resistance in the same circuit
will give the current, and once this voltage is subtracted from
the total drop for the circuit, the voltage drop across the
unknown, and thus its resistance, may be found, and displayed
on the ohmmeter. A micro-ohmmeter is an ohmmeter for the measurements
of very low resistances. |
