How can you tell they’ve got it: Ohm's Law: voltage, current, resistance?

If they’ve got it, you’ll see things like: 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). Or just try it 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?

Ohm's Law: voltage, current, resistance

Your child can use the rule linking voltage, current, and resistance. Resistance slows the current down. Double the resistance, and the current is halved.

In curriculum terms

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

Curriculum alignment

Where this fits in the official school curriculum — our best automated guess, not yet checked by a person.

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.
