How to Convert Ammeter to Voltmeter
A voltmeter measures the voltage drop between two points in a circuit. It tends to be connected to the circuit in parallel, and has high resistance so as not to usurp current from the circuit. An ammeter measures current between two points.... Read More »

Why is the ammeter in series and not the voltmeter?
The ammeter is used in series, because you want to measure the current through a circuit. The voltmeter is used in parallel, because you want to measure the voltage across a circuit. If you were to place the voltmeter in series, no current ... Read More »

You can convert an ammeter into a voltmeter by adding a series resistor. You calibrate by considering the total resistance, meter plus resister, and by considering the current that would flow if a certain voltage were applied. Generally, yo...

The theoretical resistance (idea resistance) of an ammeter is zero. With a voltmeter, it's infinitely high. In some analog meters the full scale deflection is produced by only about 50 microamps. Actually that does not change from ammeter t...
