## Emitter Current of BJT Solution

STEP 0: Pre-Calculation Summary
Formula Used
Emitter Current = Collector Current+Base Current
Ie = Ic+IB
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.
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
Collector Current: 5 Milliampere --> 0.005 Ampere (Check conversion ​here)
Base Current: 0.077 Milliampere --> 7.7E-05 Ampere (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ie = Ic+IB --> 0.005+7.7E-05
Evaluating ... ...
Ie = 0.005077
STEP 3: Convert Result to Output's Unit
0.005077 Ampere -->5.077 Milliampere (Check conversion ​here)
5.077 Milliampere <-- Emitter Current
