Then the resistance would be $2 \Omega$ (in the graph) if I understood you correctly?

Clarify question with diagram.

There will also be a gradient even if component s not ohmic. It's just that the gradient is not constant.

Then which option gives the correct answer to resistance? coordinate of v / coordinate of current or inverse-gradient of current-voltage graph?

comment Which quantity gives the resistance of a component?
I am not talking about input voltage (emf). I am talking about potential difference in a load, such as a resistor. Ohm's law states that the current through a resistor is directly proportional to the p.d. across. If I talk about a general component that do not obey Ohm's law, then resistance is just the value obtained when I divide the p.d. by the current across (by doing an experiment). Resistance is empirical. So how can resistance be calculated by taking gradient since it is not even change in voltage over current?

This doesn't answer my question. I know what Ohm's law is.

comment Why is the solar noon time different every day?
So that users will not anyhow downvote others. But I agree my error. I should have mention its the highest point of the observer at that latitude, not the zenith.
