DC-AC clamp-on ammeters use the ____ effect as the basic principle of operation.
A) Ohm
B) Seebeck
C) Lenz
D) Hall

Question

Quizplus · Accepted Answer

DC-AC clamp-on ammeters use the Hall effect as the basic principle of operation. The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. This effect can be used to measure the current flowing through a conductor without actually having to make physical contact with the conductor.
