Why can't the resistance cannot be measured with ammeters and vol...
It can be calculated by a multimeter. [aka. avometer ( a mpere v oltage o hm meter )]. A single voltmeter or ammeter could not measure resistance because this process need calculations. That means the device must be able to measure the volt... Read More »

How to measure the resistance of a resistor with a ammeter and a ...
you use a battery and unknown resistor connected in series. Connect the ammeter in series and the voltmeter in parallel, and use ohms law. However, low values of resistance need special consideration. You may need a series resistance to red... Read More »

What is the theoretical resistance of an ammeter and a voltmeter?
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... Read More »
