An SCR combines the features of ____________?
Correct answer: B. A rectifier and transistor
- A. A rectifier and resistance
- B. A rectifier and transistor
- C. A rectifier and capacitor
- D. None of the above
Explanation
An SCR combines the one-way current control of a rectifier with the switching and control action associated with a transistor. Its PNPN structure gives it this controlled-rectifier behavior.
