Dynamic resistance is the same as linear resistance true or false?
Please tell me.
Please tell me.

It's a fact that when resistance decrease, (act as an obstacle) current increase.

According to ohm's law V = I/R.
So when current increases, resistance decreases.
So when current increases, resistance decreases.

In diode internal resistance (i.e Rd = 0.7 ohm) will be same for all current.

@prasanna, I too think the same. Semiconductors do not obey ohm's law.

But diode is a non-linear device. It does not obey ohms law.

Vt/I dynamic resistance .
so r increases
so r increases

R=V/I
