🔍 Key Concepts

• Vacuum tube operation: relationship between cathode, grid, and plate (anode) and how grid voltage controls plate current • What happens when the control grid is driven very negative compared to the cathode • Difference between a condition that "cuts off plate current" and unwanted oscillations like motorboating

💭 Think About

• Which component directly controls the flow of electrons to the plate in a tube amplifier—the grid or the plate itself? • If the grid is driven so negative that plate current stops, which term best describes that abnormal state of the grid circuit? • Which option(s) describe oscillation or instability, and which describe a DC bias/fault condition?

✅ Before You Answer

• Identify which answer choices refer to oscillations or feedback problems rather than a DC bias problem • Confirm which term specifically refers to the grid being driven to an extreme negative bias so that plate current is cut off • Eliminate any option that mainly describes a normal tuned circuit rather than a fault condition
