Question 1 of 27070

Q

Effectiveness of the grid in causing changes of plate current:

🔍 Key Concepts

• Control grid function in a vacuum tube and how it affects plate (anode) current • Definition of transconductance / mutual conductance in tube or amplifier theory • Difference between resistance (ratio of voltage to current) and conductance (ratio of current to voltage)

💭 Think About

• When the grid voltage changes slightly, what parameter tells you how much the plate current changes in response? • Is transconductance usually expressed as change in current per change in voltage, or the other way around? How does that relate to the question wording? • How is plate resistance defined in terms of plate voltage and plate current? Does that directly measure the grid’s effectiveness?

✅ Before You Answer

• Verify the standard definition of transconductance (or mutual conductance) gm in tube textbooks or notes • Check whether mutual conductance is just another name for transconductance in this context • Confirm that plate resistance is defined at constant grid voltage and relates plate voltage to plate current, not grid voltage to plate current
