可在安卓获取Circuits -3000 Solved Problems的历史版本
强大的问题解决方案逐步为您提供电路问题！
A simple circuit is solved and power absorbed or supplied by each element is determined. KCL as well as Ohm's law are used in solving the circuit. positive sign convention is used in determining element powers. It is shown and discussed how a source, here current source, can be neither absorbing or supplying power. It is also mentioned that resistors are passive elements and always absorb power/energy.
Powerful Problem-Solver gives you 3,000 problems in Electric Circuits, fully solved step-by-step! The originator of the solved-problem guide, and students’ favorite offers a diagram-packed timesaver to help you master every type of problem you’ll face on tests. Problems cover every area of electric circuits, from basic units to complex multi-phase circuits, two-port networks, and the use of Laplace transforms. Go directly to the answers and diagrams you need with our detailed, cross-referenced index. Compatible with any classroom text, 3000 Solved Problems in Electric Circuits is so complete it’s the perfect tool for graduate or professional exam prep.
Problem Solvers are the most popular guide of their kind because they help students achieve their personal best tests and final grades. If you don't have a lot of time but want to excel in class, this book helps you:Brush up before tests; Find answers fast; Study quickly and more effectively; Master problems without spending hours poring over lengthy texts.
