Check understanding
- 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)
“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?”
