The correct relation between and in a transistor is

Options

  1. A= 1-
  2. B= 1+
  3. C= 1+
  4. D=1-

Correct answer

A. = 1-

Step-by-step solution

We know that = ( i_C i_E ) .....(i) and = ( i_C i_B )= i_C i_E i_E i_B = i_E i_B ....(ii) But i_B= i_E- i_C from (ii) aligned & = i_E i_E- i_C = 1- i_C i_E & = 1- aligned
