Paper “Harmonics are created by nonlinear loads that draw a current in abrupt pulses rather than in a smooth sinusoidal manner. These pulses cause distorted current wave shapes which in turn cause harmonic currents to flow back into other parts of the power system.” The problem with this phenomena is that current distortions cause voltage distortions. Which in turn creates waste in your system which is trying to supply the extra current needed to overcome the harmonics. It can also cause component

2.2.b shows the current path during the low period of the switching square wave cycle. As the MOSFET is rapidly turned off the sudden drop in current causes L1 to produce a back emf in the opposite polarity to the voltage across L1 during the on period, to keep current flowing. This results in two voltages, the supply voltage VIN and the back emf (VL) across L1 in series with each other. This higher voltage (VIN +VL), now that there is no current path through the MOSFET, forward

India to stand out a bit more. The drop in oil prices is also conducive to India, as India is one of the largest importers of oil. The country is described as a “shining star” for tackling its economic problems, thanks to reduced oil prices. India's current account deficit narrowed sharply to USD 1.3 billion or 0.2% of GDP in Q4 March 2015 from USD 8.3 billion or 1.6% of GDP in Q3 December 2014. On a year-on-year basis, the CAD registered

inventor of a product that enabled the growth of the railroad. George Westinghouse also took a great interest in the new concept of electricity. At the time, Thomas Edison and Nikola Tesla were arguing about whether Edison's direct current or Tesla's alternating current became the standard distribution system for electricity (Hartman, n.d.). This is the reason why we do not hear of Westinghouse name as much as we should. Westinghouse is the type of person who would receive a radio and take it apart
