"Bias voltage applied to the emitter electrode of a transistor offers greater stability over bias toward its base." Why? How does that actually work? My professor wants a detailed, engineering level explanation for this, and I am struggling to understand this to the degree he is asking. He says having both a positive and negative voltage source at the emitter bias is not necessary, and won't accept this as part of the explanation. Thanks!
