Ohm’s Law - Calculating Voltage, Current and Resistance
In electrical theory, Ohm’s Law is the mathematical formula for calculating the relationship between electrical voltage, current, and resistance. If a component or circuit has unaccounted electrical values, Ohm’s Law can be used to calculate these figures.
Ohm’s Law can be presented and applied in the following formula structures:
Voltage = Current X Resistance Current = Voltage / Resistance Resistance = Voltage / Current

Ohm’s Law is also commonly represented by the following diagram, often called the Ohm’s Law Triangle:
