# Bias voltage is the voltage it takes to get the diode to start conducting. Below a certain voltage, the diode will no work even in the forward direction. It is the voltage which allows the electrons and holes to overcome the depleted zone and meet with each other, creating current. Reverse Biased means that the positive end of the battery is connected with the n-type semiconductor and the negative end is connected with the p-type semiconductor. This sucks all the electrons from the n-type region and filled in all the holes in the p-type region, creating a large depleted zone. | # Bias voltage is the voltage it takes to get the diode to start conducting.
