QUESTION 4 In most cases, which two of the three BJT terminal currents are approximately equal in value? O collector current and emitter current O collector current and base current emitter current and base current O All currents are approximately equal. QUESTION 5 Calculate the collector-emitter voltage for this emitter-stabilized circuit. +15V

Task 3 a. Explain the operating principle of a BJT. b. For the given circuit below, the collector to emitter voltage of the BJT is 5.2V. Determine the current gain (B) of the transistor. BTEC 100 kn +12V 1kQ I Loughborough COLLEGE-

"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!
