Technician exam question T6D05
Subelement T6, ELECTRONIC AND ELECTRICAL COMPONENTS· Group T6D
What type of circuit controls the amount of voltage from a power supply?
- A.Regulator (correct answer)
- B.Oscillator
- C.Filter
- D.Phase inverter
WhyA regulator circuit controls the amount of voltage from a power supply. A voltage regulator circuit is specifically designed to hold a power supply's output voltage steady despite changes in load or input, answer A. An oscillator (B) generates a repeating signal, a filter (C) smooths or shapes a waveform rather than controlling its overall level, and a phase inverter (D) flips a signal's phase, none of which regulates voltage.
