🔍 Key Concepts

• AC filament (heater) supplies in audio/radio circuits • How a center-tapped transformer secondary relates each side of the filament to ground or reference potential • The idea of hum cancellation when equal and opposite voltages exist on two sides of a component

💭 Think About

• Imagine the filament with a center tap connected to a reference (like ground). What voltage does each end of the filament see with respect to that reference at any instant? • If one side of the filament goes slightly more positive with respect to the reference, what happens to the other side at that same instant? • How would having equal and opposite voltages on each side of the filament affect the net hum that can couple into the signal path?

✅ Before You Answer

• Check whether the center tap is mainly about mechanical support, voltage reduction, or symmetrical electrical reference to reduce hum • Verify if hum reduction depends on equal and opposite AC voltages around the reference point • Confirm whether statements A and B describe different aspects of the same effect, or if one adds extra information beyond the other
