When the polarity of the battery is such that electrons are allowed to flow through the diode,then the diode is said to be forward-biased. Conversely, when the battery is "backward" and the diode blocks current, then the diode is said to be reverse-biased. A diode may be thought of as like a switch: "closed" when forward-biased and "open" when reverse-biased.
What else can I help you with?
Under what conditions will a junction diode turn on?
Forward bias past the knee.
What are characteristics of an ideal diode?
An ideal diode:Passes current in one direction only. (Under forward bias).Has no leakage current (passes no current under reverse bias).Has no forward voltage drop. (No voltage loss under forward bias - a real diode has Vd~=0.7)See links for more details.
What happens when diode is supplied with a voltage higher than RIV in reverse bias?
when diode is supplied with a voltage higher than RIV in reverse bias, the diode will burn out and will have zero resistance.
Why diode drop 0.7v ouccuer in forward baised?
Diodes normally drop between 0.2 and 3.5 volts in the forward bias direction, depending on type, and forward current. The word "ouccuer" is not understood". Please restate the question.
A zener diode is invariably used with?
Reverse bias
What does forward bias on a diode?
when the positive terminal of the battery is connected to the positive terminal of the diode it is said to be in forward bias
What are the two bias conditions for a diode?
The two bias conditions for a diode are forward and reverse
What does forward bias on a diode means?
when the positive terminal of the battery is connected to the positive terminal of the diode it is said to be in forward bias
What type of bias causes a diode to conduct?
forward bias
How can you make a bypass diode?
the diode is forward bias ANSWER: A bypass diode is used to bypass circuitry as soon as the diode is forward bias by 0.6 volts The use it to bypass to prevent damage to the circuitry
How is zener diode different from a conventional diode or ideal diode?
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias 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.
Why ammeter is connected in different way in forward and reverse bias zenner diode?
The ammeter is connected in different way in forward and reverse bias zenner diode. So that all of the board will work right going forward and reverse.
Why diode conducts current in forward bias but does not conduct in reversed bias?
diode current flows only when the diode is forward biased because in reverse bias the barrier potential increases. Diode can conduct in reverse bias if applied votage is high enough to overcome the reverse bias barrier potential but it can be destructive.
What is the voltage drop of an ideal diode?
forward bias 0 volts, reverse bias infinity volts.
What are the two conditions under which a diode is operated?
A diode is operated under two primary conditions: forward bias and reverse bias. In forward bias, the positive terminal of the voltage source is connected to the anode, allowing current to flow through the diode. In reverse bias, the positive terminal is connected to the cathode, preventing current flow and allowing the diode to block current, except for a minimal leakage current.
What is the tUnnel diode?
A thin junction diode which exhibits negative resistance under low forward bias condition is known as tunnel diode.
