You learned many important things in Physics 9C MOST of which you will not directly use in ENG 17.

• Physics is a science that seeks to understand the nature of charge, current, voltage, resistance, etc.

• Engineering is a practical endeavor that focuses primarily on the BEHAVIOR of electricity in a circuit.

While physics 9C laid the foundation for your understanding of electricity and it's behavior, ENG 17 will focus on how to make electricity work for us...predictably, efficiently, and safely.  Having said that, there are certain skills that you learned in 9C that are essential for success in ENG 17 (see Physics 9C Skills Review section below).   Before you begin your study of Engineering Circuit Analysis, you should at the very least refresh yourself on the "Direct Current" topics below.  As you proceed through the course...[to be continued]
