When a diode is connected in a Forward Bias condition, a negative voltage is applied to the N-Side and a positive voltage is applied to the P-type side If this outside voltage becomesmore noteworthy than the worth of the likely boundary, approx. 0.7 volts for silicon and 0.3 volts for germanium,the potential hindrances resistance will be survived and current will begin to stream. This is on the grounds that thenegative voltage pushes or repulses electrons towards the intersection giving them the energy to get overalso, join with the openings being pushed the other way towards the intersection by thepositive voltage. This outcomes in an attributes bend of zero current streaming up to this voltage point,called the "knee" on the static bends and after that a high current flow through the diode with littleRise in the outer voltage as displayed  given below. The application of a forward biasing voltage on the junction diode brings about the depletion layerturning out to be extremely thin and narrow which results in a low impedance way through the junction accordingly permitting high flows of current The point where this abrupt expansion in current happens isShown on the static I-V qualities bend above as the "knee" point.
