Lesson Plan: Voltmeters Science • Third Year of Preparatory School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use voltmeters in electric circuits to measure the potential difference across a component in the circuit.
Objectives
Students will be able to
- recall that the potential difference between two points in a circuit can be measured with a voltmeter,
- recall what the circuit symbol for a voltmeter is,
- recall that voltmeters must be connected in parallel to a circuit.
Prerequisites
Students should already be familiar with
- the circuit symbols for several basic circuit components: a cell, a bulb, a buzzer, and a motor,
- how to draw and interpret single-loop circuits with one cell or battery,
- what electric potential difference is.
Exclusions
Students will not cover
- ammeters,
- how voltmeters work,
- resistors and resistance,
- ohmmeters,
- complex parallel circuits,
- why voltmeters must be connected in parallel,
