Current-Voltage Relationship and Ohm’s Law

What is the current-voltage relationship and Ohm’s Law?

In this post, we investigate quantitatively the current-voltage relationships in ohmic and non-ohmic resistors to explore the usefulness and limitations of Ohm’s Law, as a part of the Prelim Physics course under the module Electricity and Magnetism and sub-part Electric Circuits. The relationships that we used are W = qV and V=IR

 

The following video covers Ohm’s Law.
