“Darwin among the Machines‚” 46 years before Forster (whose story‚ “The Machine Stops‚” was published 107 years ago). It is hard to believe that two stories with a similar tone could have been written so long ago. What is even more incredible is that they both seem to relate to present day society.

But I was sort of disappointed. Humankind wanted a cruel finale. Bombs are everywhere. Merciless androids are roaming around shedding innocent blood. Deafening

transformers to determine the winding resistance‚ Req and leakage reactance‚ Xeq. The aim of this experiment is to measure‚ determine and analyses the parameters of single-phase or three-phase transformer and torque-speed characteristics of rotating machines. Besides that‚ we are required to differentiate the construction and winding of single-phase or three-phase transformer. Through this experiment‚ we have to develop the connection wiring for single-phase and three-phase transformer and
