@BvU https://www.physicsforums.com/threads/pn-junction-under-forward-bias.947962/#post-6002408 is the root cause of this mess.

Sorry for the post, but this question already has answers at https://www.physicsforums.com/threads/e-field-inside-of-a-battery.158544/

That means, in the 1st video she said we have E(field) from n side to p side. We apply larger E( from battery) against it (during forward biasing). In 2nd video, she uses +ve potential at p and -ve potential at n side. No reason provided. Back to original question. As I said earlier barrier...

please check new reply. :)

if we forward bias it, +ve terminal of battery gets - potential of diode and -ve of battery gets +ve potential of diode.(-,+) of battery(-,+), this doesn't seem to be a barrier to the battery.

But since it is the opposing potential generally we subtract them.

Outside the battery, in the conductor it is in the direction of conventional current. But what about inside? Since magnetism and electricity are related, and magnetic field inside a magnet is from South to North (outside it is North to South), i doubted for any correspondence.

If two batteries are connected such that positive terminal of one is in contact with negative terminal of other then we add the potentials so the potential will then be their sum. Similarly if a battery is connected to a pn junction diode such that positive terminal is connected to negative...
