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

Ib​ = 0.2mA.
