Question

The electromagnet in a galvanometer

A. increases the voltage in a circuit.
B. moves a pointer along a numbered scale in response to a current.
C. induces an electric current.
D. increases the current in a circuit.

Answer 1

The correct answer is B. moves a pointer along a numbered scale in response to a current.

The galvanometer is a device used for measuring small and weak electric currents. It has a part that is the electromagnet and that moves a pointer when a current is introduced. It measures smaller currents than a regular ammeter.
