Question
In a common base configuration, the transistor has an emitter current of 10 mA and a collector current of 9.8 mA. The value of base current is ______
Options
0.1 mA
0.2 mA
0.3 mA
0.4 mA
Solution
In a common base configuration, the transistor has an emitter current of 10 mA and a collector current of 9.8 mA. The value of the base current is 0.2 mA.
Explanation:
Let Ie be emitter current Ib be base current and Ic be collector current.
Ie = Ib + Ic
10mA = Ib + 9.8mA
