The next ammeter presented is an ammeter that uses a “current sink” circuit concept to measure current, resulting in a unidirectional current measurement where a current flows into the ammeter device.

There’s only one path for the current to follow. This simple circuit is like a one-bulb version of my fairy lights. The ammeter shows the current to be nought point nought six amps Watch what ...

It is then possible to test and debug the circuit by placing the probes from virtual test equipment at the desired nodes. ProtoLab includes a voltmeter, ammeter, ohmmeter, wattmeter and oscilloscope.

This is a take-off on Mr. Marian’s “Simple Micro Ampere Meter Circuit” that utilizes active circuitry and an analog meter to make sensitive DC current measurements. A reader subsequently asked if it ...

Also, the internal impedances of the measuring instrument or circuit become extremely critical ... moderately priced test equipment.The Shunt Ammeter Approach ...
