Lesson Plan: Ohm’s Law Science

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use Ohm’s Law to calculate the current through a component, the potential difference across a component, and the resistance of a component.


Students will be able to

  • use 𝑉=𝑅𝐼 in all permutations.


Students should already be familiar with

  • what charge and current are,
  • what potential difference is,
  • what resistance is,
  • how to use voltmeters and ammeters,
  • the units for charge, current, potential difference, and resistance,
  • the circuit symbols for a cell, a battery, a bulb, and a resistor.


Students will not cover

  • parallel circuits,
  • the resistance or potential difference of components in series,
  • any voltage source other than a cell or battery,
  • variable resistors,
  • any kind of non-direct current.
