V = I \times RSlope of V-I graph: \Delta V / \Delta I = RCBSE Class 10 Board Core: Activity 11.1 (Ohm's Law Verification)
George Simon Ohm stated in 1827 that the electric current flowing through a metallic wire is directly proportional to the potential difference across its ends, provided temperature remains constant.
Key Practical Exam Takeaways
- 1. Ammeter Connection: Always connected in series with the circuit. Has very low resistance.
- 2. Voltmeter Connection: Always connected in parallel across the resistor. Has very high resistance.
- 3. V-I Graph Nature: A straight line passing through the origin $(0, 0)$. The slope equals the resistance $R$.
