If collector current is (120 ~mA ) and base current is (2 ~mA ) and resistance gain is 3 , what is power gain?

Options

  1. A180
  2. B10800
  3. C1.8
  4. D18

Correct answer

B. 10800

Step-by-step solution

Current gain ( = I_C I_B = (120 ~mA ) (2 ~mA ) =60 ) Power gain (= ) Resistance gain ( ^2 ) (=(3) (60)^2=10800 )
