Forward bias and reverse bias?

For simple diode rectifier it is of great magnitude difference. while the forward voltage is .6 to .9 volts it breakdown can be in thousands of volts. It should be noted that the forward current is...

annode is negative and cathode is positive

Forward bias is when the height of the depletion layer is reduced such that a greater number of majority charge carriers have sufficient energy to overcome the potential barrier while revers bias is...

because the current push to the junction.

If you are talking about reverse biasing a diode, then you are talking about a zener diode. A zener diode, like a normal diode, has a forward bias around 0.7 volts (depending on current and...
