《电路器件及应用（第8版）》内容涉及直流电路、交流电路和常用器件的基本构成、基本工作原理、实际应用和电路故障诊断与排除。本书注重读者工程实践能力的培养，作者弗洛伊德、布什拉关注的始终是如何让读者在学完本书内容之后，能更多地解决工程实践问题，而不仅仅是知识的积累。本书既可以作为电子工程、通信、自动化、机电一体化等相关专业学生的电子技术基础教材，也是从事电子技术工作的工程技术人员的实用参考书。

弗洛伊德、布什拉编著的《电路器件及应用（第8版）》涉及大量应用实例和对电路的调试，而且是越往后的章节中应用实例所占比例越高。这些例子既包括从实际电路中抽象出来的等效模型，也有很多实际应用的电路。因此读者可以根据本书的介绍按图索骥，直接获得实际电路的解答。

本书包含大量非常精美的示意图。在很多时候，一张图的效果要远胜一段文字或一个公式。

《电路器件及应用（第8版）》对应用实例（尤其是实际电路）基本原理的分析简明且到位，用很简单的几句话就将该电路最本质的地方讲透，充分体现了作者扎实的学术功底。

本书可以有如下三方面的建议用途：

“卓越工程师教育培养计划”中电路、电子学课程的教学参考书。卓越计划很强调“做中学”，本书处处包含了在实践中学习（hands-onlearning）的思想，可很好地与“卓越计划”的教学理念匹配起来。

普通高校电路、电子学课程的教材。一方面，本书虽厚，但理论内容不多，讲授清楚简单，便于教学和自学。另一方面，随着我国成为华盛顿协议缔约国，一定会有越来越多高校培养的人才直接成为国际工程师。这就对高校的英文教学提出了要求。

电路授课教师的备课参考。如果使用得当，书中各种与电路分析基本方法密切联系的应用实例定能大大促进课堂教学质量的提高。
