1.	In a forward biased `PN`- junction diode, the potential barrier in the depletion region is of the from...A. B. C. D.
Answer» Correct Answer - D When p-n junction is forward biased, the applied voltage opposes the barrier potential. Due to it, the width of depletion layer decreases and effective barrier potential becomes less. The option `` and `` show the potential barrier in reverse bias, whereas option `` and `` show potential barrier on forward bias. Since the width of depletion layerin option `` is less than shown in option ``. Hence, the potential barrier in the deplection region will be the form as shown in option ``.
