Question

For the transistor circuit shown below, if beta equals 100, voltage drop between emitter and base is 0.7 V then value of V subscript C E end subscript will be

  1. 10 V    
  2. 5 V    
  3. 13 V    
  4. 0 V    

The correct answer is: 13 V


    i subscript b end subscript equals fraction numerator 5 minus 0.7 over denominator 8.6 end fraction equals 0.5 m A Þ I subscript c end subscript equals beta I subscript b end subscript equals 100 cross times 0.5 m A
    By using V subscript C E end subscript equals V subscript C C end subscript minus I subscript c end subscript R subscript L end subscript equals 18 minus 50 cross times 1 0 to the power of negative 3 end exponent cross times 100 equals 13 V
