Question

Arrange the following devices in increasing order of their input resistances:
(A) MOSFET
(B) BJT
(C) JFET
(D) PN junction diode

• A. (A), (B), (C), (D)
• B. (A), (C), (B), (D)
• C. (B), (A), (D), (C)
• D. (B), (A), (C), (D)

Hint:

Transistor input resistance generally depends on the type of transistor and its configuration.

Answer 1

The Correct Option is B

The input resistance ranking from highest to lowest is: MOSFET, JFET, BJT, and PN junction diode.
Final Answer: \[\boxed{(2) \, (A), (C), (B), (D)}\]
