P-N Junction Diode question from JEE Main 2025 (22 Jan, Shift 1)

Answer: (d)

1. Forward bias: anode (triangle side) potential $>$ cathode (bar side) potential.
2. (A) anode $-10\text{ V}$, cathode at a higher potential: reverse. (B) anode $-10\text{ V}$, cathode $-15\text{ V}$: forward.
3. (C) anode $5\text{ V}$, cathode $2\text{ V}$: forward.
4. (D) diode points left: cathode $-5\text{ V}$, anode $-10\text{ V}$: reverse. (E) cathode $0\text{ V}$ (ground), anode $2\text{ V}$: forward.
5. So the answer is (d) (B), (C) and (E) only.
