Y 1 0 0 1 The average value of output direct current in a half wave rectifier is A junction has acceptor impurity concentration of in the side and donor impurity concentration of in the side. What is the contact potential at the junction? ( thermal energy, intrinsic carrier concentration ) When the forward bias voltage of a diode is changed from 0.6 V to 0.7 V, the current changes from 5 mA to 15 mA. Then its forward bias resistance is
