What is Ohms?
Ohms (Ω) are the unit of measurement for electrical resistance, defining how much a material or circuit opposes the flow of electric current. Named after Georg Simon Ohm, this unit is fundamental in electrical and HVAC applications.
In electrical systems, resistance affects voltage and current flow, playing a crucial role in circuit design, wiring, and safety. High resistance can lead to voltage drops and overheating, which may cause damage to electrical components.
In HVAC systems, ohms are used to measure resistance in electrical components like motors, compressors, and heating elements. For example, a technician might use an ohmmeter to test a compressor winding’s resistance, ensuring it falls within an acceptable range for proper function.
Understanding ohms is essential for troubleshooting electrical problems, ensuring system efficiency, and maintaining safe operation in residential and commercial electrical and HVAC systems.
