Physics Question on Semiconductor electronics: materials, devices and simple circuits

For transistor the value of β\beta is 5050 then, the value of α\alpha is

A

50/5150/51

B

49/5049/50

C

51/5051/50

D

50/4950/49

Answer

50/5150/51

Explanation

Solution

We know β=α1−α,\beta =\frac{\alpha }{1-\alpha },
Given β=50\beta =50 So, 50=α1−α50=\frac{\alpha }{1-\alpha }
50−50α=α50-50\alpha =\alpha
50=51 α50=51\,\alpha
α=5051\alpha =\frac{50}{51}
