Q. When either a voltage or current is applied to the terminals of bulk solid state compound GaAs, a differential is developed in that bulk device.

  • (A) negative resistance
  • (B) positive resistance
  • (C) negative voltage
  • (D) none of the mentioned

✅ Correct Answer: (A) negative resistance
Explanation: when either a voltage or current is applied to the terminals of a sample of bulk solid state compound formed by group 5 and 3 elements of periodic table, a differential resistance is developed in the bulk device. this fundamental concept is called rwh theory.
