For the emitter current estimate: Start with a guess that VBE = 700mV V BE = 700 mV and estimate the emitter current as +15V−700mV−(−20 V) 10kΩ = 3.43mA + 15 V − 700 mV − ( − 20 V) 10 k Ω = 3.43 mA. Sanity check the VBE = 700mV V BE = 700 mV estimate by computing 26mV ⋅ ln(3.43mA 1fA) ≈ 750mV 26 mV ⋅ ln. ⁡.Applications of BJT. We know that a bipolar junction transistor is used as a switch, as an amplifier, as a filter, and even as an oscillator. Below is the list of other applications of bipolar junction transistor: BJT is used as a detector or also known as a demodulator. BJT finds application in clipping circuits so that the waves can be shaped.

It's default NPN BJT has β = 100 β = 100 and ISAT = 100aA I SAT = 100 aA. Your "EveryCircuit" link is very unlikely to use the same default model. So LTspice probably will simulate different values. Just FYI.
