Ammeter Design | DC Metering Circuits | Electronics Textbook
Ammeters Measure Electrical Current. A meter designed to measure electrical current is popularly called an "ammeter" because the unit of measurement is "amps.". In ammeter designs, external resistors added to extend the usable range of the movement are connected in parallel with the movement rather than in series as is the case for voltmeters. This is because we want to divide …
