What is Ohm?
Ohm refers to the resistance between two distinct points in a conductor. Simply put, it is the system of international or SI unit referring to electrical resistance. The word is derived from Georg Simon Ohm, a German physicist who researched and discovered the Ohm’s law.

The symbol of this term is Ω which is a common sign used in the world of electric current and other related fields. The electrical resistance of the two points of the conductor is measured by several factors. This takes place when there is a constant potential difference amounting to one volt which is applied to the two points. This in turn produces a one ampere current in the conductor. It is important to note that the conductor must not be seated on any electromotive force to get the right measurement.

The electrical resistance in ohms of the conductor is approximately in congruence to a certain range or degree of voltages. You could also measure it in temperatures and other known and qualified parameters. Ohm is a commonly used multiple or sub multiple in the electronic and electric field. There are also other terms used with it such as milliohm, kilohm, megohm and gigaohm.

This word may be irrelevant on its own especially if you are not into physics. However, when the Ohm’s law and Joule’s Law is combined, it results to a very important entity ‘“ electric power. Power is dissipated through the linear resistor and is calculated from the voltage or current and its resistance.

Ohm specifically its symbol is now used in most electronic documents especially in preparing HTML documents. However, this symbol must be used with caution and substantial knowledge since the wrong use of the Ω symbol in most document editing software could lead to confusion rather than the desired output.
