🎯 Learning Intention
I will apply Ohm’s Law to calculate voltage, current, resistance, and power.
✅ Success Criteria
☀️ Warm-Up (5 min)
“Why do gaming PCs need higher-watt power supplies?”
🧠 Mini-Lesson (10 min)
Review V = I × R and P = V × I; demonstrate formula wheel and unit conversion.
📘 Detailed Notes
| Formula | Meaning | Example |
|---|---|---|
| V = I×R | Voltage = current×resistance | 12 V = 2 A×6 Ω |
| I = V÷R | Current = voltage÷resistance | 2 A = 12 V÷6 Ω |
| P = V×I | Power = voltage×current | 24 W = 12 V×2 A |
