🔍 Key Concepts

• Input impedance and why we usually want it high or low in an amplifier stage • Output impedance and how it affects driving a load or following stages • The typical purpose of an operational amplifier (op-amp) in analog circuits (e.g., as a voltage amplifier)

💭 Think About

• If you connect a source to the amplifier’s input, would you rather the amplifier draw a lot of current from the source, or very little? How does that relate to input impedance? • If the amplifier is going to drive another stage or a load, should its output behave more like an ideal voltage source or like a large resistor? How does that relate to output impedance? • An op-amp is usually used when we want to greatly increase a small input signal. Which answer choices reflect that in terms of gain?

✅ Before You Answer

• Identify which choices have high gain (that’s a basic expectation for an op-amp). • Decide which combination of input impedance and output impedance best matches an ideal voltage amplifier: high input / low output or low input / high output? • Eliminate any choices that would cause the amplifier to heavily load the input source or be unable to effectively drive the load.
