(D) both the electric field and the carrier concentration gradient

2. A Zener diode, when used in voltage stabilization circuits, is biased in

(A) reverse bias region below the breakdown voltage
(B) reverse breakdown region
(C) forward bias region
(D)forward bias constant current mode

3.The trigonometric Fourier series of an even function does not have the

(A) dc term
