Welcome to the art of electronics, your design will have to account for the non-ideal in the real world, most practical circuits will not depend on the exact gain, but will constrain the application to...

Measuring transistor beta (hFE) - Ib anomalies explanation needed
I've been struggling with details of building accurate (\$\pm1\%\$ tolerance maximum) beta meter. The simplest idea I came with went to a diagram as shown below, with R set to a value providing a...
