🔍 Key Concepts

• Basic vacuum tube components: filament (or cathode), grid, plate (anode) • How the number of electrodes (elements) defines tube names: diode, triode, tetrode, pentode • Difference between a tube with just cathode/filament and plate versus one that also has a control grid

💭 Think About

• Count how many distinct electrodes are named in the question and match that to the type of tube. • Ask yourself: which tube type is defined specifically by the presence of one control grid between cathode and plate? • Eliminate the options that require more elements than are actually listed in the description.

✅ Before You Answer

• Verify how many electrodes a diode, triode, tetrode, and pentode each have. • Check whether the question explicitly mentions more than one grid or additional special electrodes (like screen or suppressor grids). • Confirm that the tube type you choose matches a configuration with one grid only and not multiple grids.
