In the circuit shown in figure, the base current I B is 10   μA and the collector current is 5 . 2   mA . The voltage ( V BE ) across the base and emitter is

Options

  1. A0 . 1   V
  2. B0 . 5 V
  3. C0 . 25   V
  4. D0 . 7   V

Correct answer

B. 0 . 5 V

Step-by-step solution

V B E = V C C - I B R B V B E = 5 . 5 - 10 × 10 - 6 × 5 × 10 5 = 0 . 5 V
