The collector leakage current in a transistor is 300 μA in CE
arrangement. If now the transistor is connected in CB arrangement,
what will be the leakage current? Assume β = 120.
(2) For a certain transistor, IB = 20 μA; IC = 2 mA and β = 80.
Calculate ICBO.
(3) In a transistor, IB = 68 μA, IE = 30 mA and β = 440. Determine α
rating of the transistor. Then determine the value of IC using both the
α rating and β rating of the transistor.
