The device used to adjust voltage levels in an electrical circuit is called
Correct answer: A. Voltage regulator
- A. Voltage regulator
- B. Circuit Breaker
- C. Capacitor
- D. Transformer
Explanation
A voltage regulator is an electronic device that is used to regulate and stabilize the voltage levels in an electrical circuit. Its primary function is to maintain a constant output voltage, despite changes in the input voltage or load conditions.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
