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

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.
