A 9.1 V zener diode exhibits its nominal voltage at a test current of 29 mA. At this current the incremental resistance is specified as 5 ?. The zener knee current is 1 mA.
i. The zener knee voltage, VZK.
ii. The zener voltage at a current of 10 mA and 100 mA.
iii. Based on your previous answers, what is the percent regulation with respect to the nominal zener voltage (i.e. 9.1 V)?
