The two bias conditions for a diode are forward and reverse
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
A A diode has two state either on [forward conduction .7 volts. Or reversed bias meaning the diode voltage polarity are revered or cut off, depends on the diode but it will leak some current , Anyhow that is reversed bias diode conditionForward conduction voltage can vary between about 0.6 volts and about 1.4 volts depending on the diode and the current. Also, some diodes, such as zener diodes, will conduct in the reverse direction. Reverse bias is simply where the anode is more negative than the cathode.
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
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.
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.
Forward bias past the knee.
diode does not work on zero bias
A diode is typically operated under forward bias, where the anode is at a higher potential than the cathode, allowing current to flow, or under reverse bias, where the cathode is at a higher potential than the anode, preventing significant current flow.

because the current push to the junction.
when the positive terminal of the battery is connected to the positive terminal of the diode it is said to be in forward bias
