This is basically one-half of an AC/DC power supply circuit, consisting of a line power plug, on/off switch, fuse, indicator lamp, and a step-down transformer. The reason this project idea is strongly recommended is that it may serve as the basis for the recommended power supply project in the next course (ELTR120 – Semiconductors 1). If you build the AC section now, you will not have to re-build an enclosure or any of the line-power circuitry later! Note that the first lab (step-down transformer circuit) may serve as a prototype for this project with just a few additional components. -
The Study of Electromagnetic Processes in the Experiments of Tesla
The study of electromagnetic processes in the experiments of Tesla B. Sacco1, A.K. Tomilin 2, 1 RAI, Center for Research and Technological Innovation (Turin, Italy), [email protected] 2National Research Tomsk Polytechnic University (Tomsk, Russian Federation), [email protected] The Tesla wireless transmission of energy original experiment, proposed again in a downsized scale by K. Meyl, has been replicated in order to test the hypothesis of the existence of electroscalar (longitudinal) waves. Additional experiments have been performed, in which we have investigated the features of the electromagnetic processes between the two spherical antennas. In particular, the origin of coils resonances has been measured and analyzed. Resonant frequencies calculated on the basis of the generalized electrodynamic theory, are in good agreement with the experimental values found. Keywords: Tesla transformer, K. Meyl experiments, electroscalar waves, generalized electrodynamics, coil resonant frequency. 1. Introduction In the early twentieth century, Tesla conducted experiments in which he demonstrated unusual properties of electromagnetic waves. Results of experiments have been published in the newspapers, and many devices were patented (e.g. [1]). However, such work has not received suitable theoretical explanation, and so far no practical application of the results have been developed. One hundred years later, Professor K. Meyl [2] aimed to reproduce the same experiments using a miniature, laboratory version of the Tesla setup, arguing that it can help to detect unusual phenomena that are explained by the presence of electroscalar (longitudinal) waves, namely: • the reaction on the transmitter of the presence of the receiver; • the transmission of scalar waves with a speed of 1,5 times the speed of light; • the inefficiency of a Faraday cage in shielding scalar waves, and • the possibility of wireless transmission of electrical energy. -

The activity is adapted from Kim et. al’s 2012 article in the Journal of Chemical Education (see references). Background Information: Teacher Background: Commercial products have frequently taken their inspiration from nature. For example, Velcro® resulted from a Swiss engineer, George Mestral, walking in the woods and wondering why burdock seeds stuck to his dog and his coat. Other bio-inspired products include adhesives, waterproof materials, and solar cells among many others. Scientists often look at nature to get ideas and designs for products that can help us. We call this study of nature biomimetics (see Resource section for further information). -
