About this clipart
This black-and-white technical illustration depicts a thermionic vacuum tube (diode) with a heated filament cathode emitting electrons toward a positively biased anode. The resistor labeled 'R' represents the external load in the circuit, and the dashed arrow indicates the direction of electron flow. Cross-hatching denotes metal components and vacuum envelope boundaries.
Used in educational content on early electronics, vacuum tube theory, or historical semiconductor alternatives; targets students, hobbyists, and engineers seeking foundational knowledge of electron emission devices.
