VÉRIFICATION DE LA LOI D’OHM : démonstration pratique avec une résistance de valeur fixe.

⚡ Verifying Ohm's Law with a Resistor | Complete Experiment In this video, we conduct a practical experiment to verify the famous Ohm's Law, a fundamental relationship in electricity linking voltage, current, and resistance. 🔍 Through a simple setup and precise measurements, you will understand: How to relate voltage (U), current (I), and resistance (R) Why the relationship U = R × I is experimentally verified How to plot and interpret the characteristic curve of a resistor In which cases Ohm's Law is valid (and its limitations) 🧪 Materials used Resistor (ohmic component) Adjustable DC power supply Ammeter Voltmeter Connecting wires 📊 Objective of the experiment To verify that voltage is proportional to current and that the resulting curve is a straight line passing through the origin, thus confirming the validity of Ohm's Law. 🎓 Who is this video for?
