I further declare that the work reported in this project has not been submitted and will not be submitted, either in part or in full, for the award of any other degree or diploma in this institute or any other institute or university. The major source of conventional form of electricity is through wires. One of the major issue in power system is losses occurring during the transmission and distribution of electrical power.
The main reason for power loss during transmission and distribution is resistance of wires used in grid. Tesla has proposed methods of transmission of electricity using electromagnetic induction. The Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in It is used to produce high-voltage, low-current, high frequency alternating-current electricity.
Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.
Tesla used these circuits to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high frequencyalternating current phenomena, electrotherapy, and the transmission of electrical energy without wires. Tesla coil circuits were used commercially in sparkgap radio transmitters for wireless telegraphy until the s, and in medical equipment such as electrotherapy and violet ray devices.
Today their main use is for entertainment and educational displays, although small coils are still used today as leak detectors for high vacuum systems. Procedure 1. Firstly, I gathered all the materials and arranged them on a perfectly levelled table.
Raw data values for experiment with Bulb VII. Raw data values for experiment with Bulb with aluminium sphere Table 1. DATA ANALYSIS Since in my mathematical hypothesis I formed of the square values of the radius of the wire, in order to align my results with the hypothesis, I made graphs varying the square values of the radius of the wire and the distance up to which the light emitted from the bulb and CFL in order to visually observe the type of trend between the two variables Table 2.
Radius square and range values for Bulb with aluminium sphere Table 5. Converting diameter values to squares of radius values Table 8.
Radius square and range values for CFL Table 6. As the square of the radius is increases, the value of the distance is decreasing with cubic decay, as the line of regression forms a cubic with polynomial equations of highest degree 3.
We can also observe a difference in the range of electrical appliances. The range of wireless electricity transfer of CFL with or without the aluminium sphere in the apparatus was significantly larger than that of the range of Bulb.
In the graphs, we can also see an outlier where the point indicates a positive correlation and then starts declining again. The formation of the cubic equation is justified as the r2 value almost approaches 1 which indicates that the curve correlates strongly with the scatter plot.
Graph 7. DATA ANALYSIS In order to verify the accuracy and the precision of my trials while conducting the experiment, I propagated error in the trials while performing the experiment by taking the values of standard deviation of the experimental trials of each radius of wire.
The standard deviation is then used in forming error bars in the scatter plot. Along with the taking standard deviation as the random error in my experiment, I even propagated the error in the maximum and the minimum slope which were created as a result of the standard deviation error bars. The error in the slope verified the reliability of the results further.

Strengths 4. The intervals between the thickness of the wires wire standardised and could not have been varied as they A1.
Accuracy were bought from the market. Efficiency of coil could have been improved using Accuracy was achieved to its fullest potential in my professional winding machines which could have experiment.
The experiment can be extended by using a detector coil to measure to the amount of change in magnetic flux when kept at In my experiment, I used sensitive electrical appliances such different distances from the source coil to form a as Bulbs and CFLs which indicated the slightest change in relation between the amount of mutual induction induction and hence an accurate range of wireless electricity between the coils when the distance between those transfer.
Performing my experiment in an isolated room with coils is varied. Nikola Tesla Quote 38, teslauniverse. Our history books to date do not reflect he had any success in proving this theory. He did, however, accurately predict the success of the internet and cellular phones both operating by long distance, wireless transmissions. However, his resonant inductive coupling method is applied to our short-range wireless systems. Tesla was denied funding by bankers and his theory about worldwide transmission has been denounced; however, his research was of such significance that it was confiscated by the FBI upon his death.
The magnetic field is created using inductive coupling between coils of wire or electric fields using capacitive coupling between electrodes. The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction.
The carrying fluxes that induce in the inductor can be captured by another inductive coil that can produce an induced flux between the receiver coils that coupled to the primary coil. Since this technique using magnetic field to transfer the electrical energy, the flux that produces in the primary coil must be in high density with high frequency.
