1.	Calculate the value of α for β=.2.(a) .85(b) .15(c) .23(d) .16I had been asked this question in an interview.The question is from Solid-State Devices in division Introduction to Solid-State Devices of Electric Drives
Answer» CORRECT choice is (d) .16 Easiest explanation: The relationship between β and ∝ is ∝=β/(1+β)=.2÷1.2=.16. The CURRENT gain is the RATIO of the COLLECTOR current and base current. The value of α is Ic÷IE.
