In ENIAC, 18000 vacuum tubes were used to build it in 1943. And, it was built at the University of Pennsylvania’s Moore School of Engineering with government funds.
Detailed explanation-3: -From top to bottom, the components are the anode, the cathode, and the heater filament. Vacuum tube diodes contain only two electrodes (besides the heater): A cathode and an anode. The filament heats up the cathode, producing a space charge.
