Alternating current

Gravity of Nikola Tesla explains the relation between gravitation and electromagnetic force as a unified field theory” (PESWiki.com) In addition, the earliest demonstration fluorescent lighting was his accomplishment. All of this paved the way to the current stage of electricity that is currently being used by people all across the globe. His electricity generating turbine design was used in the first hydroelectric dam that generated enough power to light a whole…

Thomas Alva Edison is known for making the first incandescent light bulb that has had a huge impact on the world today. He is important in United States history because he made electric light that plays a huge role on how we live, light is everywhere. Edison started from nothing and made his way to U.S. history. This wouldn’t have been possible without his motivation, preparation, and his contributions to change the World as we know it. Motivation Thomas Edison was motivated to finish the work…

The first part of the experiment was determining the resolution of the DAC in volts. Before a voltage was applied the noise was determined by measuring the DC offset, the reading of the DMM at an input of zero volts. This offset was removed from the recorded values in order to provide a more accurate reading of the resolution. These corrected values and their corresponding applied voltages can be found in Table 1 of the appendix. The lowest value recorded from the DMM was -9.968V and the…

In essence, Tesla coils are a high-voltage, resonant transformer circuits. They consist of the six major components (Behrend 1), namely: Primary transformer Tank capacitor Spark gap Primary coil Secondary coil Toroid Figure 1: Tesla coil (diagram) A primary transformer is a step-up transformer that takes the line voltage of the AC source and steps it up to a range between 12 kV and 50 kV at 60 Hz (Johnson 4). The efficiency of this transformer is largely dependable on the construction…

Damping to Solar Irradiation When solar irradiation increases, the PV array would equip the PV inverter with more voltage.The output current of the PV inverter should be increased to acquire more power from the PV array. To relieve the tracking error for the high-irradiation case, a high value of χ compared to Test 1 should be taken up. The best method to decrease the current deviation is to alter χ to decline the control gains to adapt PV inverter to the changed solar irradiation. The…

of 1A current. 12 V output of the step-down transformer is the RMS value and its peak value is given by the product of the square root of the two with RMS value which is approximately…

What is a circuit? How do they work? An electric circuit is a kind of path made up of wires that allows the flow of electrons. The circuit has to be made in a circular form, as the electrons must frequently move in a full loop, in which they will return to their original position and then complete the loop again. (“What is an electric circuit?”) The battery or another source of power provides the voltage, or ‘electrical push’, that makes the electrons move through the circuit. When the electrons…

The Spirit Phone After the carnage of World War I, spiritualism was undergoing a revival, and many people hoped science could provide a means to contact lost loved ones. Edison himself was not a believer and admitted he had no idea if a spirit world even existed. Edison corresponded with British inventor Sir William Crookes, who claimed to have captured images on "spirit photographs." Edison was intrigued. Edison took the idea of the telephone and the telegraph a bit further and announced in…
