Edward Hughes states that: "It is impossible to acquire a thorough understanding of Electrical Engineering principles without working a large number of numerical problems; and while doing this, students should make a habit of writing the solutions in an orderly manner, attaching the name of the unit wherever possible". This is the basis of this book. First year Electrical Engineering students will find this book as a handy companion.
