Ohm's Law: voltage, current, resistance

Apply Ohm's Law (V = IR) to calculate current, voltage, or resistance in a simple circuit, and explain that resistance opposes the flow of current

How to tell they’ve got it

Tick these off as you see them — no test required.

States Ohm's Law as V = IR and identifies the units for each quantity
Rearranges V = IR to find the unknown value given the other two
Explains that resistance opposes current flow and identifies factors that affect resistance (material, length, thickness)

Try this together

If your child doubles the resistance in a circuit while keeping the battery the same, can they predict what happens to the current and explain using the V = IR formula?

Curriculum alignment

Candidate matches to official curriculum codes — machine-suggested, unreviewed (v0.1).

This skill sits beyond Year 6 in the Australian Curriculum, so no F–6 code is matched. It also sits beyond the NSW K–6 syllabuses. It also sits beyond Level 6 in the Victorian Curriculum.
