STEP 0: Pre-Calculation Summary
Formula Used
emitter_current = ((Common emitter current gain+1)/Common emitter current gain)*Saturation current*e^(Voltage across the base–emitter junction/Thermal voltage)
Ie = ((β+1)/β)*Is*e^(VBE/Vt)
This formula uses 1 Constants, 4 Variables
Constants Used
e - Napier's constant Value Taken As 2.71828182845904523536028747135266249
Variables Used
Common emitter current gain- Common emitter current gain is highly influenced by two factors: the width of the base region, W, and the relative dopings of the base region and the emitter region.
Saturation current - Saturation current is the diode leakage current density in the absence of light. It is an important parameter which differentiates one diode from another. (Measured in Ampere)
Voltage across the base–emitter junction - The voltage across the base–emitter junction is the forward voltage between the base and emitter of the transistor. (Measured in Volt)
Thermal voltage - Thermal Voltage is the voltage produced within the p-n junction. (Measured in Millivolt)
STEP 1: Convert Input(s) to Base Unit
Common emitter current gain: 55 --> No Conversion Required
Saturation current: 0.01 Ampere --> 0.01 Ampere No Conversion Required
Voltage across the base–emitter junction: 5 Volt --> 5 Volt No Conversion Required
Thermal voltage: 25.85 Millivolt --> 0.02585 Volt (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ie = ((β+1)/β)*Is*e^(VBE/Vt) --> ((55+1)/55)*0.01*e^(5/0.02585)
Evaluating ... ...
Ie = 1.02477018010584E+82
STEP 3: Convert Result to Output's Unit
1.02477018010584E+82 Ampere --> No Conversion Required
FINAL ANSWER
1.02477018010584E+82 Ampere <-- Emitter current
