5. A transistor has an a of 0.972 and a collector-to-base leakage current of 0.073 μA. a) Find its collector-to-emitter leakage current (in microamps). b) Find the ẞ of the transistor. a c) Starting with I=: -1B + ICBO prove that IC = BIB + ICEO 1-a 1-a d) Find Ic (in milliamps) when IB = 0.03 mA. e) Find the approximate Ic neglecting leakage current.
