Question

Quizplus · Accepted Answer

AC/DC ammeters use the Hall effect as their basic principle of operation. This effect is named after the American physicist Edwin Hall, who discovered it in 1879. The Hall effect occurs when a current-carrying conductor is placed in a magnetic field, producing a voltage proportional to the magnetic field and the current. This voltage can be measured and used to determine the current flowing through the conductor, which is the principle behind the operation of AC/DC ammeters.
