Ohm's law shows the relationship between power, voltage and current (Ohm's Law). In order for a current to exist, there must be a potential difference which is proportional to the current itself (Beiser 88). Resistance, or "ohms" (represented by the omega sign below), is a constant for a given conductor. (Beiser 88)
History of Ohm's Law
Ohm's law was deveoped by Georg Simon Ohm. His interest in science came from his father, who was a skilled mechanic (Daintith 671). He published Ohm's law in 1827 in his Die galvanische Kette Mathematische bearbeit. It received little to no recognition and wasn't used for nearly 20 years (Daintith 671). In honor of Ohm's work with electricity and sound, the unite ohm was named for him.
Application of Ohm's Law
Ohm's law is applied to any electronic current. It is one of the most important equations there is. It is used in any electronic work. Ohm's are also used to measure the resistance of speakers and other audio equipment.
