From the circuit, determine the output voltage (Assume αF=1)
A. VO1=3.9v , VO2=12v
B. VO1=12v , VO2=3.9v
C. VO1=12v , VO2=0v
D. VO1=3.9v , VO2=-3.9v
Answer:A

A. VO1=3.9v , VO2=12v B. VO1=12v , VO2=3.9v C. VO1=12v , VO2=0v D. VO1=3.9v , VO2=-3.9v
Explanation: The voltage at the common emitter ‘E’ will be -0.7v, which make Q1 off and the entire current will flow through Q2.
