| Mar 27, 2014 at 8:16 | comment | added | Guill | Ayush, think of the gray section (depletion region) as a capacitor, the right side is left with a positive charge (electrons removed) and the left side is left with a negative charge (holes removed), so it acts like an internal battery with its positive end connected to the positive end of the external battery and likewise the negative side, therefore the "internal battery" is opposing the external battery! | |

| Jan 23, 2014 at 11:44 | comment | added | Ayush Pateria | I know. Electric field will be directed from N to P in the diode and from positive terminal to negative terminal in the circuit, so they are in the same direction! | |
| Jan 23, 2014 at 11:39 | comment | added | John Rennie | No, you get a negative charge to the left of the PN boundary and a positive charge to the right. | |
| Jan 23, 2014 at 11:23 | comment | added | Ayush Pateria | Exactly, but how is it opposite to the potential of battery? It's in the same direction right? | |
| Jan 23, 2014 at 11:09 | comment | added | John Rennie | Because when you pull holes away to the left you leave behind a net negative charge, and likewise when you pull electrons to the right you leave behind a net positive change. | |
| Jan 23, 2014 at 10:53 | comment | added | Ayush Pateria | How can the potential difference across the depletion layer be opposite to the battery potential? The potential in the depletion layer is from N to P and due to battery is from positive to negative terminal, so they both are in same direction, right? | |
