Ohm's Law

Ohm's Law for a Circuit Component

The current passing through a section of a circuit is proportional to the voltage across the ends of that section and inversely proportional to the resistance of the section:



Iā€” current passing through the circuit component in amperes (A);
Uā€” voltage in volts (V);
Rā€” resistance of the circuit section in ohms (Ω).
