Demonstrate the direction of current flow in DC circuits.

Demonstration should include an understanding of the characteristics, operation, and application of simple direct-current circuits and theory.

Process/Skill Questions:

• What is direct current? What are the characteristics of DC circuits?
• What types of voltage and power sources are associated with DC circuits?
• What are examples of DC circuits and applications?
• What mathematical concepts can be applied to better understand the characteristics of DC circuits?
• What is the difference between conventional theory and electronic load theory?
