Question 1 of 27070

A voltage amplifier has a calculated voltage gain of 10. Which statement correctly states the gain?

🔍 Key Concepts

• Definition of voltage gain as a ratio between output and input voltage • How a gain of 10 relates output change to input change (multiplication factor) • Direct proportionality: output change = gain × input change

💭 Think About

• If the gain is 10, what do you do to the input voltage change to find the output voltage change? • Test each option: does the described output change equal 10 times the input change? • Which choice keeps a consistent ratio of output change to input change for any value?

✅ Before You Answer

• Compute output ÷ input for each choice and see which one equals 10 • Check that the gain stays the same number (10) no matter what the input change is • Eliminate any choice where the ratio output change / input change is not exactly 10

Question 1 of 27070

A voltage amplifier has a calculated voltage gain of 10. Which statement correctly states the gain?

If the input changes 1 volt, the output changes 10 volts.

If the input changes 5 volts, the output changes 1/2 volt.

If the input changes 5 volts, the output changes 15 volts.

If the input changes 10 volts, the output changes 25 volts.
