Options
- Aconduction band just above the filled valence band.
- Bholes as majority carriers and electrons as minority carriers.
- Cproduction of n -type semiconductor.
- Dproduction of p -type semiconductor.
Correct answer
C. production of n -type semiconductor.
Step-by-step solution
array l =50 R ₁=1 k =10³ V _ i =0.01 ~V I _ e =? = I _ C I _ B =50 ; I _ C =50 I _ B V _ i = I _ B R _ i I _ B = V _ i R _ i = 0.01 10³ =10⁻⁵ I _ C =50 10⁻⁵=500 10⁻⁶ ~A array
