Georg Simon Ohm was born in 1787 in Erlangen, Germany. Georg came from a Protestant family. His father, Johann Wolfgang Ohm, was a locksmith, and his mother, Maria Elizabeth Beck, was the daughter of a tailor. Although his parents had not been formally educated, Ohm’s father was a remarkable man who had educated himself and was able to give his sons an excellent education through his own teachings. |

In 1805, Ohm entered the University of Eriangen and received a doctorate. He wrote an elementary geometry book while teaching mathematics at several schools. Ohm began experimental work in a school physics laboratory after he had learned of the discovery of electromagnetism in 1820.

In two important papers in 1826, Ohm gave a mathematical description of conduction in circuits modeled on Fourier’s study of heat conduction. These pater continue Ohm’s deduction of results from experimental evidence and, particularly in the second, he was able to propose laws which went a long way to explaining results of others working galvanic electricity.

**I = V/R (Ohm’s Law)**

The equation I = V/R is known as “Ohm’s Law.” It states that the amount of steady current through a material is directly proportional to the voltage across the material divided by the electrical resistance of the material. The Ohm (R), a unit of electrical resistance, is equal to that of a conductor in which a current (I) of one ampere is produced by a potential of one volt (V) across its terminals. These fundamental relationships represent the true beginning of electrical circuit analysis. Current flows in an electric circuit in accordance with several definite laws. The basic law of current flow is Ohm’s Law. Ohm’s Law states that the amount of current flowing in a circuit made up of only resistors is related to the voltage on the circuit and the total resistance of the circuit. The law is usually expressed by the formula V = IR (described in the above paragraph), where I is the current in amperes, V is voltage in volts ,and R is the resistance in Ohms. The Ohm, a unit of electrical resistance, is equal to that of a conductor in which a current of one ampere is produced by a potential of one volt across its terminals. |
