00:07 Ideal diode allows generous flow of current in forward bias but blocks current in reverse bias 00:59 Current through the diode is equal to Is. 02:06 In ideal diode, there is no resistance for the diode current 03:08 In reverse bias, ID is nearly zero, making it ideal. In forward bias, diode acts as a closed mechanical switch due to current flow. 04:11 A semiconductor diode only permits current to flow in one direction. 05:15 The VI characteristics for practical and ideal diodes have been plotted. 06:22 In forward bias condition, voltage across an ideal diode is 0. 07:19 Ideal diode has VD equal to 0 and current through the diode is equal to 0 in reverse bias condition.

I believe temperature refers to the ambient temperature. Does breakdown voltage changes with load current variations as that may impact the junction temperature?

since diodes are non-ohmic is it ok to apply ohm's law and calculate those answers for ideal diode?

Sir practical diode also has Generation and Recombination current, due to that also the graph slightly varies.... Am I right??

Small resistance is called Dynamic resistance

Dynamic resistance is the internal resistance of a diod in a forward condition. It influences the curve of V-I because if the forward voltage is less than barrier voltage the current tends increase gradually, but once it has passed the knee point, which is 0.7 V for diode, the forward current increases rapidly. After 0.7 V the forward dynamic resistance is very small.

In forward bias, current flows but voltage is 0 since resistance is 0 too, how is that possible to have current when voltage is 0?

In forward bias we neglected barrier potential, forward dynamic resistance, diode act like open switch so we says that voltage drop across diode is zero bc it's short circuit and current is flowing right

sir at the last moment you say that in case of forward bias (ideal)if resistance is zero then voltage across diode is zero but sir i think.....vol across diode is const it is true or false...
