The current gain for the transistor under theses conditions would be

[turbomen]

A transistor is set up in a test circit and a base current of 12μA is measured. At the same time, the collector current is measured and found to be 2.28mA. The current gain for the transistor under these conditions would be:

Could you tell me how you get the answer?

Theres two threads the same here. I answered the other one then came back looked at this one and wondered where my answer had gone.

I've tried to open a new account because I've over a limit on today. But it does not work and there is no problem to me when I tried to re-login again.

0.00228 / 0.0000012 = 1900 (gain)

is equal to 1.2micro amps - should be 0.000012A which makes the answer 190

Thank you for your kind feedback. But which is the right answer: 190 or 1900?

It makes me crazy.

190.

Heres a link to the other thread.
