What does Ohm measure?

Ohm is the unit of measurement for electrical resistance, quantifying the opposition to the flow of electric current in a circuit. When referring to the relationship between voltage (V), current (I), and resistance (R), Ohm's Law states that V = I * R, which signifies that resistance is the factor that determines how much current will flow in response to a given voltage. Thus, understanding Ohm as a measure of resistance is crucial for electrical work and calculations within refrigeration systems and other electrical applications. This concept is fundamental for electricians and technicians, as it directly correlates to how efficiently electrical components operate and how they are managed in various environments.
