According to Ohm's Law, what does the variable I represent?

In the context of Ohm's Law, the variable I is defined as current. Ohm's Law establishes a foundational relationship in electrical engineering, expressed mathematically as V = I × R, where V represents voltage, I is the current (measured in amperes), and R is the resistance (measured in ohms). Understanding this relationship is crucial for anyone working with electrical circuits and systems.

Current, in simple terms, refers to the flow of electric charge through a conductor. It is a critical parameter that influences the functioning of HVAC systems, particularly in components like motors and control circuits. Properly managing current is essential to ensure efficient operation and prevent issues like overheating or circuit failure.

While voltage refers to the electrical potential difference and resistance indicates the opposition to current flow, current is the actual movement of electrical charge. This distinction is key in troubleshooting and designing effective HVAC systems.
