Multi-range ammeter using universal shunt
What is your question.
2 volts
yes it can read both ac and dc voltage and current .AnswerThe whole point of a multimeter is that it can perform the function of an ammeter, a voltmeter, and an ohmmeter!
5 megohms
positive terminal
when we connected voltmeter in series it takes large current and voltage and the resistance is considerably decreases.this is why we had connected voltmeter in series combination.
With the pointer mid range on the scale, the reading of the multi-range voltmeter would be 125 volts.With the pointer mid range on the scale, the reading of the multi-range voltmeter is 125 volts.
why is extention
A voltmeter or a multi-meter.
If the voltage measured exceeds the voltmeter range then the voltmeter needle remains in it's maximum position until it's voltage values are considerably reduced.
if we would like to expand the range of voltmeter we should change the voltmeter resistance even to be appropriate . we should use a variable resistance to control of its value . I would extend the range of a voltmeter by adding resistance in series with it. I would extend the range of an ammeter by connecting resistance in paerallel with it.
Voltmeter connect in parallel with the circuit setting on voltmeter highest range first then to lower range. Ohmmeter we need to use the ohmmeter meter setting connect across the resistor
2 volts
If the voltage is completely unknown, a voltmeter should be set to the maximum range first, then stepped down to an accurate level.

It is someone who's vocal range can cover a range of octaves, I think it is usually at least 2... Hope this helps :)
Make a guess of what the voltage will be and set the range accordingly. If needed, change the range after measuring the voltage, to get a better reading.
