Lesson: Design of the Voltmeter Physics

Start Practising

In this lesson, we will learn how to describe the combining of a galvanometer with a multiplier resistor to design a DC voltmeter.

Lesson Plan

Students will be able to

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