Ohm's Law: voltage, current, resistance
Science · Energy · procedural
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
What mastery looks 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)
Check your understanding
If Ohm's Law: voltage, current, resistance 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?
