On what factors does collector current of BJT depends?

I_c (collector current) is independent of the value of V_CB.(voltage across base-emitter junction) That
is, as long as the collector is positive with respect to the base, the electrons that reach the collector side of the base region will be swept into the collector and will register as a collector
current.

How to Calculate Collector Current of BJT?

Collector Current of BJT calculator uses Collector Current = Emitter Current-Base Current to calculate the Collector Current, The Collector Current of BJT carried by the electrons that reach the collector region. Its direction will be opposite to that of the flow of electrons, and thus into the collector terminal. Collector Current is denoted by I_c symbol.
