Ohm's Law Cheat Sheet

Ohm’s law relates that the voltage difference between two points, the electric current flowing between them, and the resistance of the path of the current are all proportional and related to each other.

Ohm's Law explains the relationship between voltage, current, and resistance by stating that the current through a conductor between two points is directly proportional to the potential difference across the two points.

This can be expressed mathematically in terms of V the voltage difference, I the current in amperes, and R resistance in ohms.
