Technician exam question T6B11
Subelement T6, ELECTRONIC AND ELECTRICAL COMPONENTS· Group T6B
What does the term gain mean in amplifiers?
- A.The output signal voltage relative to the input signal voltage
- B.The output signal current relative to the input signal current
- C.The output signal power relative to the input signal power
- D.All these choices are correct (correct answer)
WhyGain in amplifiers can mean output voltage, current, or power relative to the input, depending on which is being measured. Gain describes an amplifier's output relative to its input, and that comparison can be expressed in terms of voltage, current, or power, so all three are valid descriptions of what "gain" means, answer D. Restricting the definition to just voltage (A), current (B), or power (C) alone leaves out the other equally valid ways gain gets specified.
