Please explain the answer.

Here, Vo = (R1 + R2/R2)(Vz + Vbe2).

Shinde Abhijeet Jeevan said: 8 years ago

Vo=(R1+R2/R2)(Vz+Vbe2).
Vo=(15+35/35)(11.2+vbe2).
Vo=17 V.

How to get VBe2?

Mnb said: 7 years ago

Here, VBe=0.7.

How? I'm getting 190?

Vo = [(R1+R2)/R2] x (Vz+Vbe).
Vo = [(15000+35000)/35000] x (11.2+0.7).
Vo = 17V.
