To the Student
Think of it!-an expected score of 75% on any exam in Electric Circuits,
with no other preparation!
The
reasoning is simple: There are only 4000 possible problems in the field (as you must know), and this book
solves 3000 of them for you!
Speaking seriously, you have here the most careful and complete anthology of examination-type problems
on the market today. In using the book, you should, of course, concentrate on the area of your maximum
weakness-the Laplace transform or whatever. But do not neglect to work problems involving familiar ma-
terial, too; you might well learn more efficient methods of handling them. The heuristic value of a clear
circuit diagram need not be stressed: if a problem in this book should carry a diagram but doesn't, be sure
to sketch out one before undertaking the solution. May your success be electric.
