The VOM is in the classification of a multimeter. This means that the one meter can do several functions. VOM stands for Volt Ohm meter. In the voltage portion, the meter has the ability to measure a variety of voltages from fractional usually up to 1000 volts. This is both AC and DC voltages. In the ohms portion, the meter has the ability to find the resistance of components. On most good multi meter there is a continuity setting that will have a sound emitted if what you are testing has continuity through it. That setting is very useful in troubleshooting control panels to locate open and closed contacts in energized and de energised relays.

Voltmeter DMM or VOM has the higher loading effect?
The VOM has the higher loading effect, because it has a lower impedance. It is typical for a VOM to have an impedance of 20K ohms per volt while the DMM has a fixed impedance of 10M ohms or 20M ohms.
What is the significance of negative values of voltage and current in the digital VOM?
The significance of negative values of voltage and current in the digital VOM is to show the accurate and full power that a particular device or equipment has in the result.

What is the main part eletricity circuit?
An electric circuit is a system of several parts. The circuit cannot function without all of them therefore there is no 'main' part. Essential parts are; power source, conducting material, load.
Which circuit has different parts of the circuit on different branches?
Any circuit that even has more than one branch is a parallel one.
