Resistor - Meaning, Definition & English Examples
A resistor is an electrical component that limits or controls the flow of electric current in a circuit. It is used to manage voltage levels and protect other components.
Definition:
A device that limits or regulates the flow of electrical current in a circuit.
Synonyms:
impedance, rheostat, limiter, regulator
Part of Speech:
noun
Antonyms:
conductor, accelerator
Common Collocations:
electrical resistor, variable resistor, fixed resistor, carbon resistor, high-power resistor
Derivatives:
resistive, resistively, resistance
Usage Tips:
Use "resistor" when referring to components in electronic circuits that oppose current flow.
Common Phrases:
load resistor, pull-up resistor, bleed resistor
Etymology:
Derived from Latin "resistere," meaning "to resist," combined with the suffix "-or" indicating an agent or device.
Examples:
- 1. The resistor controls the current in the circuit.
- 2. She replaced the faulty resistor in the amplifier.
- 3. A variable resistor adjusts brightness in LED lights.
- 4. Without a resistor, the circuit might overheat.
