Lesson Plan: Calculating the Electric Current in a Wire Science • Third Year of Preparatory School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the electric current in a simple circuit.
Objectives
Students will be able to
- recall that the coulomb is a unit of electric charge,
- recall the unit symbol for the coulomb,
- recall that the ampere is a unit of current,
- recall the unit symbol for the ampere,
- recall that one ampere is equal to one coulomb passing a point in a wire in one second,
- use .
Prerequisites
Students should already be familiar with
- what electric charge is,
- what electric current is,
- what an electric circuit is,
- the circuit symbols for some basic circuit components (e.g., a cell, a bulb, a buzzer).
Exclusions
Students will not cover
- resistors,
- Ohm’s law,
- potential difference,
- circuits with more than one path/parallel circuits,
- using ammeters,
- using voltmeters.
