Collector current when emitter current is given Formula

collector_current = Common-base current gain.*Emitter current
Ic = α*Ie

On what factors does collector current of BJT depends?

Ic (collector current) is independent of the value of VCB.(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 when emitter current is given?

Collector current when emitter current is given calculator uses collector_current = Common-base current gain.*Emitter current to calculate the Collector current, The Collector current when emitter current is given 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. Its magnitude will be proportional to eVbe/Vt. Collector current and is denoted by Ic symbol.
