🔍 Key Concepts

• Relationship between grid voltage and plate (anode) current in an electron tube (vacuum tube) • Definition of amplification factor in basic electronics / radio theory • Distinguish between electrical terms: amplification factor, power factor, and maximum inverse plate voltage

💭 Think About

• Which option describes a ratio of voltage changes that produce the same change in current in a tube? • Does the definition involve phase relationship of voltage and current (like AC power systems) or is it about tube control characteristics? • Is the quantity in the question related to how much a tube can control plate current with grid voltage, or is it about maximum voltage ratings?

✅ Before You Answer

• Verify which term is defined in textbooks as the ratio of a small change in plate voltage to the corresponding small change in grid voltage for the same change in plate current • Confirm that power factor usually refers to the cosine of the phase angle between voltage and current in an AC circuit, not to tube gain • Check that maximum inverse plate voltage is a rating/limit voltage and not a ratio of small signal voltage changes
