🔍 Key Concepts

• Triode vacuum tube structure: cathode, control grid, plate (anode) • How changing grid voltage affects electron flow from cathode to plate • Relationship between controlling current and achieving amplification

💭 Think About

• Think about what part of the triode actually controls the number of electrons reaching the plate. • How does a small change in grid voltage influence the larger plate current? • Which option best describes a function that would allow a tube to make a small signal bigger?

✅ Before You Answer

• Identify which element of the tube physically blocks or allows electrons (cathode? grid? plate?). • Decide whether the grid’s role is to completely block electrons or to control their flow in a variable way. • Check which option describes a function that directly leads to signal amplification, not a secondary effect like neutralization.
