Lesson Plan: Alternating-Current Ammeters Physics • Third Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the construction of ammeters using the thermal expansion of conducting wires to measure alternating currents.
Objectives
Students will be able to
- identify the components of a hot-wire ammeter and their configuration,
- explain the functions of the configured components of a hot-wire ammeter,
- recognize the disadvantages of the hot-wire ammeter.
Prerequisites
Students should already be familiar with
- galvanometers,
- ammeters,
- alternating current,
- resistive dissipation,
- thermal expansion.
Exclusions
Students will not cover
- calculations of alternating current.
