Zener Diode

Zener diodes are mostly used for

• rectifier circuits

• Filter Circuits

• solar cells

• Voltage regulator circuits

Principle behind using zener diode as a voltage regulator is

• Increase in input voltage decreases the voltage drop across the resistor by supplying constant voltage supply through the through the output

• Decrease in input voltage increases the voltage drop across the resistor by supplying constant voltage supply through the through the output

• Increase/decrease in input voltage Increase/decreases the voltage drop across the resistor by supplying constant voltage supply through the through the output

• None of these

What type of diode is in the picture?

• rectifier

• silicon

• zener

• tunnel
