NEET Physics Semiconductor Electronics Questions Solved


In a PN-junction diode not connected to any circuit

(a) The potential is the same everywhere

(b) The P-type is at higher potential than the N-type side

(c) There is an electric field at the junction directed from the N- type side to the P- type side

(d) There is an electric field at the junction directed from the P-type side to the N-type side

(c) At junction a potential barrier/depletion layer is formed, with N-side at higher potential and P-side at lower potential. Therefore there is an electric field at the junction directed from the N-side to P-side
