Question

A transistor has a base current of 1 mA and emitter current 90 mA. The collector current will be(a) 90 mA(b) 1 mA(c) 89 mA(d) 91 mA

Answer 1

Ur answer is 91

HOPE IT HELPS YOU :)

Answer 2

In an electric circuit of transistor is mainly used to amplify the electricity and this amplified amount of electricity is known as the collector current of that particular transistor.

To calculate the collector current amount we simply have to calculate the difference between the emitter current and the base current.

And according to the data mentioned in the question,the collector current will be:

=90-1

=89mA.

That's why the correct answer of this question is option C.
