Lesson: The Moving-Coil Galvanometer Physics
In this lesson, we will learn how to describe the application of the motor effect to the measuring of electric current by a moving-coil galvanometer.
The arm of a moving-coil galvanometer is deflected through an angle of when the current through the galvanometer is 180 μA. What is the sensitivity of the galvanometer? Answer to two decimal places.
The diagram shows a cross-section of a moving-coil galvanometer. Which of the following diagrams most correctly represents the magnetic field around the galvanometer core?
The diagram shows a moving-coil galvanometer. The terminals of the galvanometer are connected to a direct-current source. Which of the terminals A or B connects to the positive output of the source?
