At equilibrium, in a p-n junction diode the net current is
Option: 1 due to diffusion of majority charge carriers.
Option: 2 due to drift of minority charge carriers.
Option: 3 zero as diffusion and drift currents are equal and opposite.
Option: 4 zero as no charge carriers cross the junction.
At equilibrium, in a p-n junction diode, the net current is zero as diffusion and drift current is equal and opposite.
