- RCA Radiotron Vacuum Tube, Model WD-11, 1923-1924 - Vacuum tubes appear in older radios, televisions, amplifiers, computers, and other electronic devices. Their function: to amplify and strengthen weak electronic signals. Typical tubes are sealed glass bulbs evacuated of gas, allowing electron flow to be influenced by an interior cathode, plate and grid. Perfected in 1906 by Lee De Forest, the vacuum tube was the genesis of a communications revolution.

- Short Circuited Rotor for Experimental Westinghouse Induction Motor, 1889-1893 - Nikola Tesla's name is inseparable from the development of alternating current electricity--particularly with regard to polyphase transmission, but especially with regard to the induction motor. His motor, patented in 1888, was the first practical AC motor. George Westinghouse licensed Tesla's motor patents that same year--enabling the Westinghouse AC lighting system to become a real competitor with direct current systems.

- Westinghouse Type A Wattmeter, 1903-1904 - In the late 1800s, companies that supplied electricity to consumers needed a way to measure how much customers used -- and then charge them accordingly. Inventive electrical engineers developed various methods to measure electric power. Induction meters that employed magnetic fields to rotate a disc or cylinder to register energy usage would become the standard. Continued improvements made these wattmeters more compact and reliable.
