SUMMARY
The discussion focuses on calculating the resistance of a light bulb using Ohm's Law. Participants measured a voltage drop of 2.25V across the bulb and a current of 0.24A flowing through it. The resistance was calculated using the formula R = ΔV/I, confirming that the voltage reading from the multimeter (2.25V) is the correct value to use. The calculated resistance values were 9.3 ohms and 3.13 ohms depending on the voltage interpretation, with the consensus being to use the direct measurement from the multimeter.
