DOnly from anode to cathode (forward biased) — blocks reverse
Answer & Solution
Correct answer: D. Only from anode to cathode (forward biased) — blocks reverse
**PN junction diode:** forward bias (anode +, cathode -)
→ conducts (V_F ~0.7V for Si, 0.3V for Ge).
Reverse bias → very small leakage current.
Breakdown at high reverse V. Applications: rectifiers, voltage protection, signal demodulation.
