It depends upon whether it is analogue or digital, as they work in completely different ways, and each will have completely different components. As there are far more than three 'parts' to either type of instrument, you need to rephrase your question and be more specific about what you want to know.
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.
Typical VOMs can measure both AC and DC.
0.5 amps
Ohm is the unit for electrical resistance. The definition is given by Ohm's Law: resistance = voltage / current; in SI units: ohms = volts / amperes. For example, a resistance of 1 ohm would result in 1 ampere of current for every volt applied.
Ohms Law.
A meter that can be used to measure multiple ranges of currents and voltages is called a multimeter. A common type of multimetera combination voltmeter, ohmmeter and milliammeteris abbreviated VOM

If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
the answer is ohms
as a tester
Volt-Ohm Meter
The unit of measure for voltage is volt. Ohm measures resistance.
The " Ohm " is. 1 ohm is the resistance across which 1 volt of EMF appears when the current through it is 1 Ampere.
one volt applied across one ohm of resistance causes a current flow of one
One ohm is equivalent to one volt per amp.
The unit of measure for voltage is volt. Ohm measures resistance.
