Electronics - Diodes and Applications - Discussion

@Anub.

Lets say we have a P.N junction diode,
Lets connect it in forward bias. ok.!

It means + of battery is connected to "P"(majority holes)
- of battery is connected to "N"(majority electrons).

So when when v increase the incoming current, electrons(-ve charge)in P gets attracted towards the positive terminal(+)of battery and holes(+ve charge)get attracted to Negative terminal(-ve). So the width of barrier increases.

Kindly explain, how can barrier potential get increases with increase in current when both are inversly proportional to each other.

In complex mode diode in forward bias so increse the cureent then increse the output voltage.

When we increase supply voltage the conductivity also increases so mobility of charge carriers also increases then barrier potential decreases
