Ohm's Law

Ohm's law is a physical law that establishes a relationship between voltage (V), resistance (R) and amperage (I).

Ohm's law reads as follows: The current through a conductor is directly proportional to the potential difference between the ends.

(To keep it a bit more simple we used V for voltage, in the original Ohm's law formula they use U.)

$$V = R • I‌$$

With this knowledge you're also able to use the formula to calculate the amperage in a circuit.

$$I = V/R‌$$

Or to calculate the resistance in a circuit.

$$R = V/I‌$$
