🔍 Key Concepts

• Vacuum tube operation during the nonconducting (cutoff) portion of the cycle • Meaning of inverse plate voltage and how it relates to plate (anode) and cathode potentials • Definition of mutual conductance (transconductance) in tube theory

💭 Think About

• Ask yourself: which term specifically refers to a voltage rating/limitation between plate (anode) and cathode, especially under reverse or nonconducting conditions? • Consider what mutual conductance actually measures: is it a voltage, a current, or a ratio relating change in plate current to change in grid voltage? • In the phrase "maximum negative anode voltage with respect to the cathode," which choice is consistent with a maximum allowable reverse voltage on the tube’s plate?

✅ Before You Answer

• Verify which term is defined in tube datasheets as a maximum voltage rating (often abbreviated as MIV or similar) between anode and cathode. • Confirm that mutual conductance is expressed in units of mhos (siemens), not volts, and represents a conductance value, not a voltage limit. • Check whether the described quantity is a single well-known tube rating or a combination of two unrelated concepts.
