Voltage drop in diode

the depletion region is resposible for voltage drop
all that is fine
but in forward bias there is no depletion region hence there can be no voltage drop
but it is mentioned in my book that the voltage will drop by .7 volt
how come this can happen


also i have many doubts in transistor amplifiers
waiting for reply's

Re: Voltage drop in diode

The forward voltage drop in a diode is given in thread:

It is a function of both current and temperature.
