Calculate the value of ∝ using the data: Ic=18 mA, IE=17 mA.(a) 1.05(b) 1.47(c) 1.89(d) 2.55This question was addressed to me during an interview for a job.This interesting question is from Solid-State Devices topic in section Introduction to Solid-State Devices of Electric Drives

Answer» RIGHT answer is (a) 1.05

The EXPLANATION: The VALUE of ∝ is Ic÷IE. The current GAIN is the ratio of the COLLECTOR current and base current. ∝=Ic÷IE=18÷17=1.05.
