Define the resistance of a resistor
WebJul 11, 2024 · Resistance (also known as ohmic resistance or electrical resistance) is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). The larger resistance, the greater the barrier against the flow of current. When the potential difference is applied to a ... Webresistor: [noun] a device that has electrical resistance and that is used in an electric circuit for protection, operation, or current control.
