🔍 Key Concepts

• Dielectric: a material that does not conduct electricity but can support an electric field • Difference between good insulators (like glass, ceramic, mica) and a perfect dielectric • Think about whether any matter at all is truly 100% non‑conductive under all conditions

💭 Think About

• Ask yourself: can any solid material begin to conduct if voltage, temperature, or frequency are high enough? What does that say about it being truly ‘perfect’? • Consider which option is fundamentally free of charged particles that can move, rather than just strongly resisting their movement. • Think about how high‑voltage physics and radio engineering texts define a ‘perfect dielectric’ in theory – is it usually a real material or an idealized condition?

✅ Before You Answer

• Before choosing, decide which option is theoretical/ideal rather than just ‘very good’ in practice. • Review the concept that even excellent insulators like glass, ceramic, and mica can break down electrically at sufficiently high voltages. • Check which option would have no atoms or free charge carriers present at all, and how that relates to the term ‘perfect dielectric’.
