WebAug 8, 2009 · This MCQ appeared in KEAM (Engineering) 2009 question paper. The collector signal current ic is given by. ic = vc/Rc = 2 V/ 2 kΩ = 1 mA. Since the current amplification (βac) of the transistor is 200, the base signal current ib is given by. ib = ic /βac = 1 mA /200 = 0.005 mA = 5 μA. The input signal is the voltage drop (ibRb) produced ...
