Electrical Resistance｜Glossary
This page is part of the Electrical Glossary for RF and coaxial systems.
What Is Electrical Resistance?
Electrical resistance is a property that opposes the flow of electric current in a circuit.
It represents how difficult it is for electric charge to pass through a material or component.
Resistance is measured in ohms (Ω) and is commonly used to control current, divide voltage, and protect circuits.
In electronic systems, resistors are widely used components designed to provide specific resistance values.
Resistance in RF and Coaxial Systems
In RF and coaxial systems, resistance contributes to signal loss and heat generation within conductors and components.
Although RF systems primarily focus on impedance, resistance is one of its key components and affects overall signal attenuation.
At high frequencies, resistance increases due to the skin effect, where current concentrates near the conductor surface.
Contact resistance at connectors can also impact performance, leading to signal degradation and reduced reliability.
Understanding resistance is important for minimizing loss and maintaining signal integrity in RF systems.
