A voltmeter works by measuring the amount of volts of electricity being given by an electrical line or battery. A digital voltmeter has an easier to read display and is also more accurate.
You mean fastest? Digital voltmeter gives reading in seconds.
Digital voltmeter has high input impedence.

the special purpose digital voltmeter are devloped for measurement of temperatur. They are called as the digital thermometer .
Lots of them, maybe hundreds.
the voltmeter use a SLR camera because this is the latest camera and the good light and good shot of a picture
Basic adc
it is scalar as readings on Any scale is scalar.
The primary application of a digital DC voltmeter is to display the amount of DC current present in a circuit. This is particularly handy when troubleshooting problems.
If it's an analog voltmeter, it will work as soon as a voltage is applied. If it's a digital meter, it will need to be turned on first, but will respond instantly once it is powered up.
