Current electricity, mechanics, sound and wave: Physics made simple

t's a well known that truly, PHYSICS is one of the important subject for science, because of what PHYSICS simply talks about, due to the wide scope of the subject, alot of students find Its difficult to make good grades on the subject, and most teacher find it difficult to complete the syllabus.
This book will enable students to understand and assimilate the topics during the time of study, and can also help during a proper and thorough revision, as the book is devided into section based on the topics in physics,

this make the book an ideal hand book for students, this book also exposes the students to the exact pattern of how questions are been set for any exam.
brief about the book, All charges whether free or bound, were considered to be at rest.The Charges in motion contain or constitute an electric current. And Such currents occurs in naturally in many or some certain situations.
Lightning is one such example or phenomenon in which charges flow from the clouds to the earth through the atmosphere,
Also sometimes with disastrous results. The flow of charges in lightning is not continuous or steady, but in our everyday life we see many devices where charges flow in a continuous and steady manner, like water flowing smoothly in a river. A torch and a cell clock are examples of such devices. In this book we shall study some of the basic laws concerning steady electric currents.
