Physics (10 points for first correct answer)?

A series circuit consists of two loads and a 6 V power source. Readings are taken to measure the resistance of each load. The 6 V power source is then replaced by a 9 V power source. How does the resistance of each load change after the change in power supply?









1. The resistance of each load increases by a factor of 1.5.



2. The resistance of each load remains the same.



3. The resistance of each load decreases by a factor of 1.5.



4. The resistance of the first load increases, but the resistance of the second load decreases.Physics (10 points for first correct answer)?

2 Resistance is independent of voltage or current for passive loads.Physics (10 points for first correct answer)?
it depends of the load nature... if it's a resistor it will be the same.
