Is v directly proportional to i (from v=
or is v inversely proportional to i (from p=iv)

First of all, I is proportional V according to the Ohm's Law. R is merely a constant you need to obtain an equation. However, it is true that R changes with temperature and pressure, therefore Ohm's Law is only applicable in an invariable environment. Also this constant R is different for different materials.

So, do not get confused.

Ohm's law is not a universal law, please remember that as well. Some materials do not follow it and we call them non-ohmic conductors. I hope I helped! ^-^

step-by-step explanation: a third of 24 is 8, 8 times 3 is 24 so 8 - 2 would be 6

this is a good question! i'll do some research and come back when i have the answer!
