Lesson Plan: Cells in Parallel Science • Third Year of Preparatory School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the total emf of a set of cells that are connected in parallel.
Objectives
Students will be able to
- recognize that cells can be connected in parallel, with each cell aligned the same way,
- recognize that when identical cells are connected in parallel, the total emf is equal to the emf of each cell,
- recall what the circuit symbol for a cell is.
Prerequisites
Students should already be familiar with
- what potential difference is,
- the idea that potential difference is measured in volts.
Exclusions
Students will not cover
- the rules for potential difference, current, or resistance for any other types of circuit components,
- non-direct current,
- Ohm’s law,
- internal resistance.
