Can failing be counted as an accomplishment? Thomas Edison the inventor of the light bulb and many other inventions would say yes. One of Edison’s co- workers said that it was a shame that he spent so much time on the new battery and had produced no results. Edison thought of his failures in a different and optimistic way and replied with ‘“Results? Why‚ man‚ I have gotten a lot of results! I know several thousand things that won’t work!”’ Edison’s good attitude and will to keep going brought along

Alternating current bridges….it’s applications and various perspectives revealed….. ALTERNATING CURRENT BRIDGES:- INTRODUCTION:- A bridge circuit is a type of electrical circuit in which two circuit branches (usually in parallel with each other) are "bridged" by a third branch connected between the first two branches at some intermediate point along them. The bridge was originally developed for laboratory measurement purposes and one of the intermediate bridging points is often adjustable when

By “electric current”‚ I mean by the rate at which electric charges moves through a circuit‚ the electric charges can either be ions or electrons. They are measured in ammeters and the unit that is measured in is ampere which is the number of charges that passes through per second. There are many factors which would affect the electric current‚ like the voltage of

Since the flux is sinusoidal‚ r.m.s = (form factor*average e.m.f )/turns But form factor = (r.m.s value)/(average value) =1.11‚ Then r.m.s value of E.m.f = 1.11*4F*max.Flux = 4.44F*max.Flux‚ But max .flux = B_m*A r.m.s value of E.m .f in primary turn (Tp) = 4.44F*B_m*A*T_p NOTE: Bm is assumed to be 15000Wb/m. F = Frequency of A.C input/ Output F=50 Hz By introducing stacking factor (10-8) and Tp factor (0.9) then we have Number of turns per volt = N_T/V =7/A =7/3.75=1.87turns/volts

BREAKDOWN IN SOLID DIELECTRIC The requirements of good dielectric: o Low dielectric loss‚ o High mechanical strength‚ o Free from gaseous inclusions‚ and moisture‚ o Resistant to thermal and chemical deterioration. Solid dielectrics have higher breakdown strength compared to liquids and gases. When breakdown occurs‚ solids get permanently damaged while gases fully and liquids partly recover their dielectric strength. Breakdown mechanism varies depending

Global EMC Shielding Market 2014-20180280035Electromagnetic Compatibility (EMC) is the ability of electrical equipment to perform efficiently in an electromagnetic environment without being affected or influenced by other devices in its proximity. EMC shielding is a protection provided to electrical and electronic devices to protect them from EMI. EMI refers to the phenomenon where electromagnetic radiation affects the performance of electrical and electronic equipment. EMC shielding is used across
