Question

Consider a zener diode with the model shown. Not that Vz and Rz are known.
a) Find an expression for the current through and the voltage drop on the diode

-for no load (RL=infinity)

-for a given finite load RL.

b) Find the numerical values of current through and voltage on the diode in the presence and absence of a load when:

Vb=12V Vz=4V   Rs=1kΩ Rz=40Ω RL=1kΩ

uitu the Nuo d Shown Rz tue eradt thkough aud Rs and UO

Answer 1

For mo load RstR z Z. Total R = Rs + R3 RL I IL -

Hope this helps!
