NCERT-Class-12-Physics-Part-1

by NCERT

All of us have the experience of seeing a spark or hearing a crackle when we take off our synthetic clothes or sweater, particularly in dry weather. This is almost inevitable with ladies garments like a polyester saree. Have you ever tried to find any explanation for this phenomenon? Another common example of electric discharge is the lightning that we see in the sky during thunderstorms. We also experience a sensation of an electric shock either while opening the door of a car or holding the iron bar of a bus after sliding from our seat. The reason for these experiences is discharge of electric charges through our body, which were accumulated due to rubbing of insulating surfaces. You might have also heard that this is due to generation of static electricity. This is precisely the topic we are going to discuss in this and the next chapter. Static means anything that does not move or change with time. Electrostatics deals with the study of forces, fields and potentials arising from static charges.

disappointing. plot was shit, language was hard to understand, characters were so boring and there were some weird symbols that just appeared out of nowhere without any explaination. big loophole in plot. would not recommend.

Thanks to this book, I was able to comprehend the concepts of electricity and magnetism. The diagrams provided in this book are precise, simple and explained thoroughly. The authors describe each physical phenomenon with such care as not to confuse the readers. This book is a thoughtfully created guide to dip your toes into the world of Electricity and Magnetism.

Though the solved examples and back exercises are nothing to write home about.
