Unit 5 - Current and Resistance

Last unit you learned about capacitors, a common circuit component you'll find on the exam. In this shorter unit, you'll learn about resistors, an even more common circuit component. But before learning about resistors, you need a formal understanding of current, both on a molecular level and a practical level. Finally, you'll finish the unit with an understanding of power usage of a resistor. Next unit you'll put these components together into an actual circuit.

Completing all lessons in this unit takes approximately 5 hours.
