sharp reverse breakdown function
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
in the negative biasing it gives the constant voltage irrespective of limited current.......the voltage it provides in the negative biasing is known as 'zener voltage' due to this property zener voltage is used as voltage regulator........voltage regulator is a circuit which gives constant output even the input is changing.
in the negative biasing it gives the constant voltage irrespective of limited current.......the voltage it provides in the negative biasing is known as 'zener voltage' due to this property zener voltage is used as voltage regulator........voltage regulator is a circuit which gives constant output even the input is changing.
Zener diodes attempt to keep the voltage across their terminals constant. They are often used in power supplies to regulate output voltage to 3, 9, 12, 15, etc. volts. Unlike a typical diode, current may be allowed to flow in either direction to regulate the output voltage.

The zener diode is neither a voltage amplifier nor a current limiting device but can be used in oscillator circuits to supply a constant output voltage.
For answering this question we have to consider the constant voltage drop model of the diode which says that if voltage across diode is less then its cut in voltage than assume diode to be open circuit and if it is greater then assume diode to be short circuit.Till the input voltage is less than the cut in voltage, diode is open circuit(thus no current through the circuit). Thus entire input voltage appears across the diode as output.When input voltage is greater than or equal to cut in voltage, then short circuit the diode. Thus, there will be no voltage drop across the diode as output.Thus cut in voltage decides when to consider the diode open circuit and when short circuit. It decides when the diode will have output when it will not.
Work in reverse bias.(breakdown at a particular voltage to keep the volt. constant so used as voltage regulator) same as diode when forward biased.
A Zener diode regulates voltage in electronic circuits by allowing current to flow in reverse when the voltage exceeds a certain threshold, maintaining a constant output voltage. This helps stabilize the voltage and protect sensitive components from damage.

If the DC source biases the diode off, then the output will be zero. If it biases the diode on, then the output will be DC, with the voltage being nearly the same as the input voltage.
a diode and it has a constant voltage across it ANSWER: acts as a voltage regulator if enough current flows to create a breakdown voltage.
