what is zienerdiode

Subject: Physics, asked on 24/4/16

In case of a p-n junction diode at high value of revers bias , the current rises sharply. The value of the reverse bias is known as :
  1. cut-in
  2. zener voltage
  3. inverse voltage
  4. critical voltage

You still have not solved my problem as when you add two equations as given in answer given by expert you get
VBB+Vi=VBE+IBRB+DELTA IB(RB+ri) .Problem still remains unresolved.
How u have arrived at this equation: Vi=DELTAIB(RB+ri) . Please see the problem asked earlier.

Transistor as an amplifier topic, how this equation is arrived;
VBE+vi=VBE+IBRB+DELTA IB(RB+ri) this equation is given by you in meritnation as well as NCERTBOOK ,PAGE NO.498.Please solve this problem.
