For a CE transistor amplifier, the current amplification factor is 59 and the emitter current is 6.6 ~mA . Then the base current is

Options

  1. A0.11 ~mA
  2. B1.1 ~mA
  3. C11 A
  4. D0.11 ~A

Correct answer

A. 0.11 ~mA

Step-by-step solution

E mitter current, I _ E =6.6 ~mA Current amplification, =59 aligned & I _ C = I _ B = I _ E & I _ B = 1+ I _ E & I _ = 1 1+ I _ E = 1 1+59 6.6=0.11 ~mA aligned
