đ Key Concepts
⢠Compare the roles of cathode, grid, and plate in a conventional triode tube to the roles of emitter, base, and collector in a transistor
⢠Think about which element controls the current flow in each device
⢠Consider which elements are mainly responsible for current supply, control, and collection in both devices
đ Think About
⢠In a triode tube, which element emits electrons, which one controls their flow, and which one collects them?
⢠In a transistor, which element is the main source of charge carriers, which one controls the current, and which one receives most of the current?
⢠Once you match the control, source, and destination roles between the tube and transistor, do all three pairs line up consistently?

Before You Answer
⢠Identify clearly: which element is the control element in each device (grid vs. base)
⢠Verify: which elements act as the main source and main receiver of current (cathode vs. emitter, plate vs. collector)
⢠After matching each pair, check if every single statement in A, B, and C is correct before deciding whether D can be true
