I had this small question today when working with an ammeter. Since an ammeter must be in series of the circuit, I had to constantly break the circuit to take current readings. Whereas, when using the voltmeter, just placing the probes on the device to take an immediate voltage reading works.
Since all devices follow ohm's law, assuming a purely resistive circuit, can't I place a voltmeter and an ohmmeter in parallel to a device to take its current reading?
If yes, why don't we do this often and use ammeters? If no, well why not?
