What is the formula for ohms law? - ✔✔I=V/R I is the current through the conductor
(amperes), V is the potential difference measured across the conductor (volts), and R is
the resistance of the conductor (ohms).
Ohm's law - ✔✔Ohm's law states that the current through a conductor between two
points is directly proportional to the potential difference across the two points.
where I is the current through the conductor in units of amperes, V is the potential
difference measured across the conductor in units of volts, and R is the resistance of
the conductor in units of ohms. Ohm's law states that the R in this relation is constant,
independent of the current.[3]
