BUILDING ELECTRICAL CIRCUITS
This presentation discusses series and parallel circuits. It begins by stating the learning objectives which are to understand the basic symbols used in circuits, the differences between series and parallel circuits, and how current behaves in each. It then provides an overview of electrical circuits and their components. The key differences between series and parallel circuits are explained, namely that series circuits have one single path for current to flow, while parallel circuits have multiple paths. Examples of each type of circuit are shown and quick quizzes are included to test understanding.
