The instrument used to measure electrical current is called an ammeter, which is actually a shortened form of 'amp meter'. The current is measured in amperes. In scientific labs, a much more sensitive instrument called a galvanometer is used to measure very small currents.
A current is passed through a resistor and the voltage drop is measured on the other side. It follows Ohm's law by a given current and voltage you can measure the resistance of a resistor by V=IR.
Total resistance is 120 ohms. The 120VAC will be split evenly over this 120 ohm load, so every ohm of resistance gets a volt. So there will be a 40 volt drop across the 40 ohm resistor.
If there is a meter that shows volt and ohms then it is showing you the amount of voltage and resistance there is. However these meters are two separate devices with different uses.AnswerA 'volt ohmmeter' ('VOM') is a term used in North America to describe what is known, elsewhere, as a 'multimeter'. A multimeter combines the functions of a.c. and d.c. voltmeter, ammeter, and ohmmeter. The advantage of a multimeter is that it avoids the necessity of having to carry about six separate measuring instruments.

Capacitance is measured in Farads. "The unit... in ohm and meter" does not make sense.
It stands for digital volt-ohm meter
sensitivity of a multimeter is defind as the smallest value that can be measured by the meter . some time it may also be given the recprocal of full scale defflection and resistance . volt/ohm.
Continuity tester, volt meter, clamp on amp meter, megger and ohm meter.
The answer is volt.
The pressure is checked with a gauge, the electronics are checked with an appropriate scan tool and a volt/ohm meter.The pressure is checked with a gauge, the electronics are checked with an appropriate scan tool and a volt/ohm meter.
you can ck the speed sensor with a volt meter while you have someone spinning the wheel. make sure your volt meter reads mv`s
If you place an OHM meter across a resistor, it will read resistance. An OHM meter set to read voltage will read any voltage present. So, if you pick up a resistor, connect it to a volt meter, in theory, no voltage will be present. Unless you're feeding some sort of electricity through it. I'm certainly not an electrical engineer, I do however use a volt/ohm meter occasionally. A volt/ohm meter is a dual/multi purpose piece of equipment.
