Define zener diode-voltage regulator
Describe briefly the term zener diode? Describe briefly the term voltage regulator?
Expert
The break-down area of a p-n diode can be made extremely sharp and nearly vertical diodes with almost vertical breakdown area are named as zener diodes. A zener diode operating in the breakdown area is equal to a battery. Due to this current through zener diode can alter but the voltage remains steady. It is this steady voltage that has made the zener diode an significant device in voltage regulation.
Voltage regulator: The output remains steady despite alters in the input voltage due to zener effect.
