Emitter Current using Collector Current and Current Gain Solution

STEP 0: Pre-Calculation Summary

Formula Used

Emitter Current = ((Common Emitter Current Gain+1)/Common Emitter Current Gain)*Collector Current
I_e = ((β+1)/β)*I_c
This formula uses 3 Variables

Variables Used

Emitter Current - (Measured in Ampere) - Emitter Current is the amplified output current of a bipolar junction transistor.
Common Emitter Current Gain - Common emitter current gain is influenced by 2 factors: width of base region W, and relative dopings of base region and emitter region. Its range varies from 50-200.
Collector Current - (Measured in Ampere) - Collector current is an amplified output current of a bipolar junction transistor.

STEP 1: Convert Input(s) to Base Unit

Common Emitter Current Gain: 65 --> No Conversion Required
Collector Current: 5 Milliampere --> 0.005 Ampere (Check conversion here)
