ok i was doing an experiment on p-n diodes
i was asked to plot graph of voltage across resistor VS voltage of diode
with a DC source varying from 0 to 30V
resistor 1k ohm
The Attempt at a Solution
i understand the forward bias where the graph shows that the voltage across the diode is very small at 0.5V max even when the voltage across the resistor is increasing like mad. it shows that most of the voltage drop occurs over the resistor and not the diode which is right
but the problem is the 2nd part. on the reverse bias.
why is the potential drop equal on both the resistor and the diode? namely 30 V each. since it is series connection, how can the total potential drop of 60V be more than my source's max 30V ?
have i reached breakdown voltage yet? because i read that avalanche braekdown usually occurs at >50V?
so my graph is still just reverse bias only?
