Answer Posted / anahita
a zener diode can be used as a voltage regulator to provide
a constant voltage from a source whose voltage may vary
over sufficeient range.The zener diode of zener voltage Vz
is reverse connected across the load Rl across which
constant output is desired.The series resistance R absorbs
the output voltage fluctuations so as to maintain constant
voltage across the load .It maintain resistance longly.
