Ohm's Law Formula

Voltage = Electric Current*Resistance
V = I*R

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. According to this current across the conductor is directly proportional to the voltage and inversely proportional to the resistance. Its expression is V=IR. where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms
