Please view the youtube video below: This is not a homework problem. The reason seems rather weird. Though the video seems incomplete, I would like to know the reason why 39.2 Ohms showed up. It seems rather weird. I know that resistance does not depend on the Voltage or the current if I am not wrong. If I have a bulb it has different resistance in different places? If I have a resistor measured lets say 1 Ohm. If I change the voltage or the current the resistance will change? It does'nt really make sense to me. Though I would like to point out that temperature dependence is what could be affecting the resistance. But by the amount that would V^2/R. Could someone please assist me in answering the question posed in the video/ explain the reason given by the Professor?
