Question
Consider an n-p-n transistor amplifier common emitter configuration. The current gain of the transistor is 100. If the collector current changes by 1mA, what be the change in emitter current
Options
A.1.1mA
B.1.01mA
C.0.01mA
D.10mA
Solution
ᐃIb = 
mA = 0.01 mA
ᐃc = ᐃIc + ᐃIb = 1 + 0.01 = 1.01 mA
mA = 0.01 mAᐃc = ᐃIc + ᐃIb = 1 + 0.01 = 1.01 mA
