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
💬 Discuss
✅ Correct Answer: (B) giving a positive feedback
Explanation: oscillators require a device that has high instability. to achieve this condition, transistors are used with a positive feedback to increase instability.
