![]() When the positive terminal of the battery is connected to the N-type semiconductor and the negative terminal of the battery is connected to the P-Type semiconductor, then it is called Reverse Bias or Reverse Biasing. What is Vcc, Vss, Vdd, Vee in Electronics?.Why NPN Transistors are mostly used than PNP Transistors?.In forward bias condition, the PN Junction diode act as a conductor and the flow of current depends upon the applied forward voltage. On the other hand, the n-type region is connected to the negative terminal of the battery, so electrons in the n-type region also repel and move towards the junction.Īs a result, the width of the depletion decreases and the potential barrier is broken down, so currents start flowing through the diode. So, as in forward bias condition, the p-type region is connected to the positive terminal of the battery, the holes in the p-type region repel and move towards the junction. We know that the same polarity always repels to each other and opposite polarity always attracts each other. In this case, the width of the depletion region also very less. ![]() ![]() In forward bias condition, the potential barrier of the PN Junction diode reduces and can conduct current.
