Ohm's Law

Output: Press calculate

Formula: I = V / R

Ohm's Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship: I = V / R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms (Ω).

Ohm's Law is a fundamental principle in the field of electronics and electrical engineering. It is used to calculate the resistance required to create specific current flow in electric circuits. It also serves to deduce the other two quantities, current and voltage, when two are known.
