Emitter Current given Base Current Solution

STEP 0: Pre-Calculation Summary

Formula Used

Emitter Current = (Drain Current+1)*Base Current
I_e = (I_d+1)*I_B
This formula uses 3 Variables

Variables Used

Emitter Current - (Measured in Ampere) - Emitter Current is the amplified output current of a bipolar junction transistor.
Drain Current - (Measured in Ampere) - Drain Current below threshold voltage is defined as the subthreshold current and varies exponentially with gate to source voltage.
Base Current - (Measured in Ampere) - Base Current is a crucial current of bipolar junction transistor. Without the base current, the transistor cannot turn on.

STEP 1: Convert Input(s) to Base Unit

Drain Current: 0.3 Milliampere --> 0.0003 Ampere (Check conversion here)
Base Current: 0.077 Milliampere --> 7.7E-05 Ampere (Check conversion here)

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.
