Identify the biasing in B and C ?? Share with your friends Share 0 Shobhit Mittal answered this Dear Student,in forward biasing the barrier potential is small then the unbiased junction.hence th e graph C is of the forwar biased PN junction.in reverse biased mode the barrier potential is very high from the unbiased potential barrier.hence the graph B is of the Reverse biased junction diode.Regards 0 View Full Answer
