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
Typical age: 12–13 years
“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?”
