How is an ammeter converted to a voltmeter?
An ammeter can be converted into a voltmeter by connecting a resistor in series with it. This works best if the ammeter is a very sensitive ammeter, such as in the micro ampere range. More commonly, a voltmeter (or sensitive ammeter) is converted into an ammeter by placing a small resistor in parallel with it. ...
To increase the range of a dc ammeter you would use a?
To increase the range of an ammeter, you connect a very low impedance resistor in parallel with the ammeter. ...

Which has higher resistance an ammeter or micro ammeter?
Micro ammeter has higher resistance. use ohm's law.. Say the voltage applied is 1 V. then for the ammeter.. I=1A, V=1V R=1 ohm for the micro ammeter.. I=0.000001, V=1V R=1000000 ohms ...
