How is a resistor measured
WebSurface Mount Resistors: These resistors are small and lightweight, and they are designed to be mounted directly on the surface of a printed circuit board (PCB). Resistor Values: The value of a resistor is measured in ohms (Ω), and it represents the amount of resistance the resistor provides in a circuit.
