According to OM sources, the temperature of the conductor is proportional to the voltage of its two ends, while the temperature and other physical conditions remain unchanged. In the field of physics, the formula refers to the difference between electrical current, resistance and voltage difference. If there is a difference between the two ends of a conductor, then the electrical current takes place. Depending on the quantity of this flow, depending on how much voltage difference is applied at the two ends of the conductor, conductive and its temperature. George Simon O'Mahm gave the following formula about the connection between the electrical current flowing through a conductive wire and the voltage difference between its two ends, which is known as OM's formula. If V is a voltage source and R is a resistor through which the amount of electric current is flowing, then according to the formula of O: V = IR.
