The zener voltage of a zener diode is kept at desired value by
Adjusting the input voltage
Adjusting the input current
By connecting an appropriate resistance in series
Changing the level of doping
Answers (1)
As we learn
To draw the characteristics of zener diode and to determine its reverse break down voltage -
*initially V1 increased, I, also increases a little then Vo increases. At a breakdown increase of V1, increases I1 by large amount so Vo = V1 - R1 I1 becomes constant. VO = VI -RL I1 constant.
Const. value of VO gives reverse breakdown Voltage
Correct option is 4
