What is Transistor Collector Current?
If a small current is applied to the base pin of the NPN transistor, it will turn ON the transistor and allow the current to flow from collector to emitter. Applying only a small current in base, but the flow is a large current through the Collector emitter pins. This larger current flow through the collector pin is known as the collector current.
Transistor Current Calculation Formula
Ic = β × Ib
The transistor’s current is calculated using the fundamental equation of Ic = β × Ib, where Ic is the Collector current, Ib is the base current, and β is the transistor’s hFE value. This HFE value can be found in the datasheet of the transistor.
Example Calculation
Ib = 2 mA
β = 100 then the Ic will be calculated by
Ic = 2 × 100 = 200 mA
