H4P2 ZENER REGULATOR
Assume that VI=13.0V, RIN=1 kΩ, and vi=50.0mV.
ow, we can insert a Zener diode into the circuit, as shown below. The Zener diode is a nonlinear device and a piecewise-linear approximation to its i-v characteristic is shown graphically below.
For RL=2 kΩ the value of VO (in Volts) is: I found it - 5.001 but how to calculate vo? I did some formulas but they aren't working.
Trying to figure out how to post the graphic here, beacause I don't see how.

This is the graphic. I only want to know how to calculate the noise voltage. The rest answers I already wrote.

I already did the exercise :)
