Variables Used

Emitter Current - (Measured in Ampere) - Emitter Current is the amplified output current of a bipolar junction transistor.
Saturation Current - (Measured in Ampere) - Saturation Current is the diode leakage current density in the absence of light. It is an important parameter which differentiates one diode from another.
Common-Base Current Gain - Common-base current gain α is related to β common-emitter current gain and its value is less than 1 because collector current is always less than emitter current due to recombination of electrons.
Base-Emitter Voltage - (Measured in Volt) - Base-Emitter Voltage is the forward voltage between the base and emitter of the transistor.
Thermal Voltage - (Measured in Volt) - Thermal Voltage is the voltage produced within the p-n junction.

Why is collector current less than emitter current?

If the Emitter-Base junction is forward biased and the Collector-Base junction is reverse biased, the voltage across the device causes electrons from the emitter to flow to the collector. In this, electrons pass through the P-type lightly doped base region and some of the electrons recombine with holes. Therefore, the collector current is less than that of the emitter current.
