Q

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

🔍 Key Concepts

• Voltage gain is the ratio of output voltage change to input voltage change • A gain of 5 means the output changes 5 times as much as the input (in the same direction) • Use the basic relationship: Gain = Output ÷ Input

💭 Think About

• Write the formula for voltage gain and plug in the given gain of 5, then solve for Output in terms of Input • Test each choice by asking: if Input = X, what does Output have to be for the gain to stay equal to 5? • Compare the ratio (Output change ÷ Input change) in each option and see which one equals 5

✅ Before You Answer

• Verify that Gain = Output change ÷ Input change, not the other way around • Check the numerical ratio in each option to see which equals 5 • Confirm that the correct option shows the output changing by a larger amount than the input, consistent with a gain greater than 1
