Question

7. Express Ohm’s law both by a mathematical formula and by a graph.

Answer 1

this is ohms law
here if u find any mistake then plzz comment

Answer 2

According to ohms law, at constant temperature, the current flowing through circuit is directly proportional to the potential difference between across its ends.
That is; I ~ V (at contant temperature)
or; V = R × I
where is resistant.

And graph,
