In a p-n junction under equilibrium, the net current is:
At equilibrium (no bias), diffusion and drift currents balance each other, resulting in zero net current across the p-n junction. This follows from latest NCERT 2026-27 principle explaining the concept clearly for NEET students in simple steps as per rationalized syllabus.
