My question is about the reverse bias graph. In reverse bias graph the current is plotted along negative direction. But current can't be negative so how is it plotted like that. Also in zener diode, how the electrons are stripped off and from which side, p-side or n-side.

HOW CAN THE OUTPUT RESISTANCE BE HIGH?
Ro=Vce/Ic
here Ic is in order of 10^-3 amperes then when we divide it would become a constant * 10^3 ohms
then too it is given that the resistance will be in the order of 10^5 ohms
pls give the answer as soon as possible iam greatly confused.
