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

$\rule{200}{2}$

$\huge\boxed{\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R:-}}}}}$

(d) 91 mA

Answer 2

Answer:

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.
