Emitter Current given Collector Current Solution

STEP 0: Pre-Calculation Summary

Formula Used

Emitter Current = Collector Current/Drain Current
I_e = I_c/I_d
This formula uses 3 Variables

Variables Used

Emitter Current - (Measured in Ampere) - Emitter Current is the amplified output current of a bipolar junction transistor.
Collector Current - (Measured in Ampere) - Collector current is an 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.

STEP 1: Convert Input(s) to Base Unit

Collector Current: 5 Milliampere --> 0.005 Ampere (Check conversion here)
Drain Current: 0.3 Milliampere --> 0.0003 Ampere (Check conversion here)

Emitter Current given Collector Current Formula

Emitter Current = Collector Current/Drain Current
I_e = I_c/I_d

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.
