A: Both diodes have the same curve in the forward direction however if the zener voltage is reverse it will breakdown at a particular voltage and remain conducting at the voltage. A regular diode will not do that the to voltage will fold back after breakdown to any voltage

When a 10mA forward bias current and the voltages at the anode and cathode of a diode in a circuit are found to be the same what is the diode most likely to be?
With a 10mA forward bias current, if the voltages at the anode and cathode of a diode in a circuit are found to be the same, then the diode most likely to be shorted.
What is the purpose of the zener diode in a power supply?
to limit the voltage or regulate the same.
What is zener diode and for what it is used?
Zener Diode is nothing but a Crystal P-n junction diode in which the P type and n-type layers are heavily doped.Zener diode is mainly used as voltage regulator its forward charaqcteristic is same as normal p-n junsction diode but its reverse Characteristic is different that when the reverse region reaches knee region in spite of changes in current the voltage remains the same
Operation of zener diode?
A: A zener is a diode that when connected in the reverse mode current direction it will breakdown to a predetermined voltage any further increasing voltage the breakdown will remain practically the same.
What is material made of a zener diode?
SILICON same as any other diode but with different characteristics
Will a zener diode work the same as a germanium diode?
No. An ordinary diode, be it silicon or germanium, conducts in one direction only, whereas a zener diode conducts in both directions, but at different voltages. An ordinary diode is used to rectify, using its forward bias characteristics, while a zener diode is used to regulate, using its reverse bias characteristics.
What is the forward voltage of a silicon based zener diode?
It would be 0.7V, the same as any other silicon diode; except for one thing, most zener diodes are manufactured with a reversed diode in series with them. When the zener is operated in its normal zener breakdown mode this reversed diode conducts, letting the zener operate. When the zener is operated in its forward biased mode this reversed diode prevents conduction. Thus most zeners have no forward voltage.

What is zener dioide?
Zener diode can be defined as diode which allows current to flow in the forward direction in the same method as an ideal diode, but will also allow it to flow in reverse direction when the voltage is above definite value known as the breakdown voltage
Is it can say as a 4.9v zener diode If you connect seven 0.7v silicon diodes in forward bias in series?
When the design says 4.9v zener diode that is all I would put. The more complicated an alternative you try the more things that can go wrong. A silicon diode is not the same as a zener diode, and cannot be used to replace a zener, with reasonable expectation that the circuit will continue to operate as designed.
How replace branches of diode with zener diode?
You do not want to replace diodes with zener diodes. They are not the same type of device, and the design objective is not the same.
What is the purpose of the zener diode in a power supply?
to limit the voltage or regulate the same.
When a 3.3 V zener diode is parallel with a 7 V zener diode what is the break down voltage?
Since they are in parallel, the 3.3V zener diode will "kick in" first when you reach 3.3V, and the circuit will pretty much act the same as if the 7V zener diode isn't there at all.
What is V-I characteristics of zener diode?
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.
When a 6 V zener diode is series with a 12 V zener diode what is the effect?
If they are both connected in the correct direction, and they are both rated for close to the same power dissipation (approx the same physical size), then you have created an 18-V zener diode.
