A reverse-biased semiconductor diode acts like a/ an

Correct answer: C. Open switch.

  • A. Inductor.
  • B. Conductor.
  • C. Open switch.
  • D. Closed switch.

Explanation

A reverse-biased semiconductor diode acts like an open switch because it does not allow current to flow under reverse bias conditions. This occurs because the diode's internal electric field opposes the flow of charge carriers. Option C is correct as it describes this behavior. Option A is incorrect because an inductor's function is unrelated to the diode's operation. Option B is incorrect because a conductor allows current flow, contrary to a reverse-biased diode. Option D is incorrect because a reverse-biased diode does not allow current to pass, unlike a closed switch.

About PN Junction

A PN junction forms when p type and n type semiconductor regions meet, creating a depletion layer and a potential barrier. The topic covers forward and reverse bias, diode current voltage characteristics, breakdown and rectification, while distinguishing an ordinary junction diode from a transistor formed from multiple junctions.
