A voltage amplifier has a calculated voltage gain of 5. Which statement is true concerning input and output voltages?

AI Explanation
The correct answer is A) If the input changes 2 volts, the output changes 10 volts. This is correct because a voltage amplifier with a calculated voltage gain of 5 means that for every 1 volt change in the input, the output will change by 5 volts. Therefore, if the input changes by 2 volts, the output will change by 2 x 5 = 10 volts. The other options are incorrect because they do not accurately reflect the relationship between the input and output voltage changes based on the stated voltage gain of 5. For example, option B and D would be correct if the voltage gain was 2, not 5.
