Preface

The
main purpose of this handbook is a HANDS-ON APPROACH in learning DC circuits.

In
each section, a component is introduced and then a software/hardware circuit
will follow. The software circuit can be implemented by electronic circuit
design and simulation software such as Multisim ®.

The
main goal of this handbook is to create a vast visualization of the working
function of the DC electronics circuitries. Based on my experience in teaching
electronics, students had more problems with setting up the hardware circuits
than software circuits. Therefore, one of my main intentions in writing this
handbook is to guide the students through setting up a complete wiring of the
circuits.

This
handbook is a COMPREHENSIVE COVERAGE of the practical working of the DC
circuits and can be used as DC electronics textbook/lab manual in DC
electronics course.
