Q. In transistor oscillators, FET and BJT are used. Instability is achieved by:

(A) giving a negative feedback
(B) giving a positive feedback
(C) using a tank circuit
(D) none of the mentioned
Correct : Option (B)

Explanation: 
 oscillators require a device that has high instability. to achieve this condition, transistors are used with a positive feedback to increase instability.
