Modern Physics 6 Question 23
25. In a - junction diode not connected to any circuit
(a) the potential is the same everywhere.
(1998, 2M)
(b) the
(c) there is an electric field at the junction directed from the
(d) there is an electric field at the junction directed from the
Show Answer
Solution:
- At junction a potential barrier/depletion layer is formed, with
-side at higher potential and -side at lower potential. Therefore, there is an electric field at the junction directed from the -side to -side.
