The differences among the various electric meters, except for digital meters, are not in the meter movements, but in the internal circuits of the meter and in how the magnetic fields are created.

Question

Quizplus · Accepted Answer

The primary differences among various electric meters (excluding digital meters) lie in their internal circuitry and the methods used to generate magnetic fields, rather than in the meter movements themselves. Meter movements are generally similar, utilizing electromagnetic principles to measure electrical consumption, but the specifics of how each meter achieves this can vary significantly based on its design and intended use.
