Inductive measurement is being discussed.Technician A says a standard DMM can be used to directly measure current flow more than 10 amps.Technician B says a DMM measures current flow by detecting the strength of the magnetic field created by current flowing through a conductor.Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Question

Quizplus · Accepted Answer

Technician B is correct because a DMM (Digital Multimeter) measures current flow indirectly by detecting the magnetic field strength around a conductor, which is a principle of inductive measurement. Technician A is incorrect because a standard DMM typically cannot directly measure current flows more than 10 amps without the risk of damaging the meter or its fuse; for high current measurements, a clamp meter or an external current transformer is usually required.
