Little Help

Your questions are rather vague.

1. capacitive reactance reduces as the frequency increases, so the output voltage will increase with frequency at first and then remain constant at higher frequencies.

2. I don't understand this question at all. Do you mean what will happen to the emitter current when the signal frequency increases? If so, the DC current will not change.

The two qeustions are multiple choice: 1) In theorical terms, as the frequency of a signal increases, the voltage at the output side of a coupling capacitor:A) increases-B) decreases-C) remains the same-D) is dependent upon the dc bias applied to the capacistor.


2)For a transistor operating normally in an operational circuit, the emitter current: A)is opposite in direction from the collector current- B)is opposite in direction from the base current.- C)equals the collector current minus the base current.- D)equals the collector current plus the base]

if any one can help me with this questions i'll greatly appriciated.
