Answer:
The answer is C) amperemeter
Step-by-step explanation:
An ammeter is made up of a galvanometer which is constructed with an indicator needle, a spring, a coil, and 2 permanent magnets and its operation is based on magnetism. The needle is attached by a spiral spring to the axis of a rectangular coil, which is suspended due to the magnetic field of the magnets.
Because the coil is controlled by the magnetic poles of the magnets when a current passes over it generates its own magnetic field which makes it turn depending on the meaning and force of this electrical intensity.
