What is Ohm's law?

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
The resistor's current I in amps (A) is equal to the resistor's voltage V in volts (V) divided by the resistance R in ohms (Ω): V is the voltage drop of the resistor, measured in Volts (V).​​​​​​​
