Go Collector Current = Current Gain*Base Current

Common Emitter Current Gain Formula

Current Gain = Collector Current/Base Current
A_i = I_c/I_b

How does current flow in a transistor?

Current freely flows from collector to emitter. Cut-off -- The transistor acts like an open circuit. No current flows from collector to emitter. Active -- The current from collector to emitter is proportional to the current flowing into the base.
