Lesson: Design of the Ammeter Physics • Third Year of Secondary School

Join Nagwa Classes

Attend live Physics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to describe the combination of a galvanometer with a shunt resistor to design a DC ammeter.

Students will be able to

describe the appropriate connection of a galvanometer and shunt resistor to produce an ammeter,
explain the required resistance ratio of the galvanometer and shunt,
calculate the measurement range of an ammeter from the current required for a full-scale deflection of the galvanometer and the ratio of the resistance of the galvanometer to the shunt.
