Ohm's Law, named after the scientist Georg Simon Ohm, defines the relationship between Voltage (V), Current (I), and Resistance (R) in circuits. It states that electric current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R).
Key Points:
- Formulas: V = IR, I = V/R, R = V/I
- These formulas enable calculations for voltage, current, resistance, and power (P).
- Illustration: Two circuits with 12V source and different resistances show Ohm's Law in action.
- Calculation Example: For a 110Ω circuit, I ≈ 0.11A; for a 220Ω circuit, I ≈ 0.5A.
