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. It is also directly proportional to emitter current.

How to Calculate Collector Current using Emitter Current?

Collector Current using Emitter Current calculator uses Collector Current = Common-Base Current Gain*Emitter Current to calculate the Collector Current, The Collector current using Emitter Current is the current that is because of 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. Its magnitude will be proportional to e_Vbe/Vt. Collector Current is denoted by I_c symbol.

How to calculate Collector Current using Emitter Current using this online calculator? To use this online calculator for Collector Current using Emitter Current, enter Common-Base Current Gain (α) & Emitter Current (I_e) and hit the calculate button. Here is how the Collector Current using Emitter Current calculation can be explained with given input values -> 5000.845 = 0.985*0.005077.
