Question
The reaction between α and β parameter of a transistor is given by
Options
`alpha = (1 - beta)/beta`
`alpha = (1 + beta)/beta`
`alpha = beta/(1 - beta)`
`alpha = beta/(1 + beta)`
MCQ
Solution
`alpha = beta/(1 + beta)`
Explanation:
`alpha = I_c/I_e`
= `I_c/(I_c + I_e)`
= `(I_c/I_b)/((I + I_c)/I_b)`
= `beta/(1 + beta)`
