What does the term OHMS represent in electrical terminology?

The term OHMS is a unit of measurement that specifically represents resistance in an electrical context. It is named after the German physicist Georg Simon Ohm, who formulated Ohm's Law, which relates voltage (V), current (I), and resistance (R) in an electrical circuit. According to Ohm's Law, resistance (measured in ohms) is defined as the ratio of voltage (measured in volts) to current (measured in amperes). This means that ohms quantify how much a component resists the flow of electric current. Understanding resistance is crucial for oil heat technicians because it affects how electrical systems perform, including the safety and efficiency of heating equipment.

In contrast, voltage refers to the potential difference that drives current through a circuit, power pertains to the rate at which energy is used or transferred, and current is the flow of electric charge. While all these concepts are interrelated in electrical systems, OHMS specifically denotes resistance.
