🔍 Key Concepts

• RC coupling vs direct coupling between transistor amplifier stages • How a capacitor behaves for DC (steady) versus AC (signal) conditions • The role of biasing (DC operating point) in each transistor stage

💭 Think About

• Compare what happens to the DC voltage at Q1’s collector and how it affects Q2 in circuit A versus circuit B • Think about what the coupling capacitor does to DC and to the AC signal when placed between Q1 and Q2 • Ask yourself: which option actually describes an advantage gained by inserting a capacitor and resistors between the stages?

✅ Before You Answer

• Verify which choice explains separating DC bias from AC signal coupling between the two stages • Eliminate options that only restate a basic property of capacitors without mentioning any practical benefit to this amplifier design • Check that the correct option applies to both stages working together, not just to a single component like the capacitor alone

In the illustrated circuit, what is one advantage of the RC coupling over a direct coupling? See illustration EL-0048.

as the frequency decreased the capacitive reactance (Xc) increases

the amplifier becomes more efficient at lower capacitance.

the arrangement allows the coupling of the signal while it isolates the biasing of each stage.

good frequency response.
