Tesla Coils
A Tesla coil is an electrical resonant transformer, resonant transformer circuit designed by inventor Nikola Tesla in 1891. It is used to produce high-voltage, low-electric current, current, high-frequency alternating current, alternating-current electricity. Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled tuned circuit, resonant electric circuits. Tesla used these circuits to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high frequency, high-frequency alternating current phenomena, electrotherapy, and the wireless power transfer#Tesla, transmission of electrical energy without wires. Tesla coil circuits were used commercially in spark-gap transmitter, spark-gap radio transmitters for wireless telegraphy until the 1920s, and in medical equipment such as electrotherapy and violet ray devices. Today, their main usage is for entertainment and educational displays, although small c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Questacon
Questacon – The National Science and Technology Centre is an interactive science communication facility in Canberra, Australia. It is a museum with more than 200 interactive exhibits relating to Science, technology and society, science and technology. It has many science programs that are intended to inspire the children of Australia to love science. Complementing the main museum, Questacon Science Circus is an extensive science outreach program. Each year, the Science Circus engages with more than 100,000 people, travels 25,000 kilometers, runs professional development courses for 600 teachers, and visits about 30 remote aboriginal communities as well as hospitals, nursing homes, and special schools. History Questacon is an interactive science centre that began as a project of the Australian National University (ANU), in spare space at the Ainslie Public School in Canberra. It opened with 15 exhibits and was staffed entirely by volunteers and by ANU physics lecturer Prof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
