Question

A transistor is used in a linear amplifier arrangement. The transistor has small and large signal current gains of 200 and 175,
respectively, and bias is arranged so that the static value of collector current is 10 mA. Determine the value of base bias eurrent
and the change of output (collector) current that would result from a 10 HA change in input (base) current.
