Question

How can i determine ohms law by altering the power supply? What are the sources of error in this experiment ?

Answer 1

Ohm’s law describes the fundamental way in which electrical circuits behave. There is a direct relationship between current, resistance and voltage. Ohm’s law also states that resistance is a constant independent of both current and voltage.[1] If you have some wire that you don’t know the resistance of, you can calculate it simply by measuring the current and voltage running through the wire and then plugging it into Ohm’s law.
