ohm's law parooves that the current is directly proportional to the voltage as the resistance is constant during the experiment and it is also prooving that it relates inversly with the resistance as the voltage remains constat for the whole experiment.
I dont know what aapartus needed in the experiment so i am very sorry about that . So procedures , tools , disscussions , results and diagrams all are within the experiment so i hope someone can really help you .
