✓Lesson Snapshot
Student Objective
I can explain voltage, current, and resistance and use Ohm’s law to solve simple circuit problems.
Main Activity
Analyze simple circuits, practice multimeter expectations, and calculate voltage, current, resistance, or power as directed.
Deliverable
Ohm’s law practice and circuit notes
Tools / Materials
Notebook, calculator, simple circuit examples, multimeter demonstration if available
1ProblemUnderstand the challenge and why it matters.
Many mechanisms are powered or controlled electrically. Motors, sensors, lights, and controllers all depend on circuits that must be safe, reliable, and matched to the load they operate.
2ConceptLearn the engineering idea or skill.
Voltage is electric potential difference, current is the flow of charge, and resistance opposes current. Ohm’s law connects these three values, and electrical power connects voltage and current.
3ApplyUse the skill in a guided task.
Solve a set of simple circuit problems and identify what would happen if resistance increases, voltage decreases, or the load draws too much current.
4DocumentRecord your evidence and decisions.
Show formulas, substitutions, units, and explanations. Include one labeled circuit sketch showing source, load, switch, and measurement points.
5ReviewCheck quality and identify your next step.
Check that your answers include units and that your explanation connects the math to actual circuit behavior.
