our Professor asked me to prove the equation of dynamic resistance of diode , he want me to explain him where did the equation come from !
the equation is this : [r]_{}[/AC]=[n.[V]_{}[/T]]/[/_{}[/Q]]
r is for resistance
[V]_{}[/T] stands for thermal voltage
_{}[/Q] is the I at operating point of diode
so if you know how it has made , please let your friend knows it too
