What does the term "OHM" represent in electrical terms?

The term "OHM" is a unit of measurement that represents resistance in an electrical circuit. Resistance is the property of a material or component that opposes the flow of electric current. The relationship between voltage, current, and resistance is described by Ohm's Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor. Specifically, Ohm's Law can be formulated as:

[ I = \frac{V}{R} ]

where ( I ) is the current measured in amperes, ( V ) is the voltage measured in volts, and ( R ) is the resistance measured in ohms. Understanding resistance is crucial for troubleshooting and ensuring the proper functioning of electrical systems, as high resistance can lead to reduced current flow and affect the performance of heaters and other components in heating systems.
