Q. In microwave oscillators, negative resistance transistors and diodes are used in order to generate oscillations in the circuit.

(A) true
(B) false
(C) ---
(D) ---
Correct : Option (A)

Explanation: 
 in microwave oscillator, for a current to flow in the circuit the negative impedance of the device must be matched with positive impedance. this results in current being non-zero and generates oscillation.
