Variables Used

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)
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.
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

Saturation current: 0.01 Ampere --> 0.01 Ampere No Conversion Required
Common emitter current gain: 55 --> 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

I_B2 = (I_s/β)*(e^(V_BE/V_t)) --> (0.01/55)*(e^(5/0.02585))

Evaluating ... ...

I_B2 = 1.82994675018901E+80

STEP 3: Convert Result to Output's Unit
