🎯 Learning Intention

I will apply Ohm’s Law to explain how voltage, current, and resistance work together in a DC circuit and how these relationships affect real computer components.

✅ Success Criteria

• I can define voltage (V), current (I), and resistance (R) accurately.
• I can use the Ohm’s Law equation (V = I × R) to solve a basic circuit problem.
• I can explain why incorrect voltage or amperage damages hardware.

☀️ Warm-Up (5 min)

“If a power supply sends 12 volts through a circuit with 6 ohms of resistance, how much current flows?”

(Write your guess first, then solve after the lesson.)

🧠 Mini-Lesson (15 min) — Electricity as the Lifeblood of Technology

Concept Overview:

1. Voltage (V): Electrical pressure pushing electrons through a circuit.

2. Current (I): Flow rate of electrons (measured in amperes).

3. Resistance (R): Opposition to flow (measured in ohms, Ω).

4. Ohm’s Law: The relationship between all three →V=I×R

   V=I×RV = I \times R

Key IT Connection:

Power supplies convert AC to DC and regulate voltage to prevent overloading components.

Too much voltage = fried circuit. Too little = unstable system.
