3.2 Circuit Types, Series and parallel introduction

Series and Parallel Circuits: Discover How Electricity Flows

You will explore how series and parallel circuits work, compare their key differences, and connect these concepts to the electrical systems you use every day.

What You'll Learn

You learn that circuits need a closed path for current flow.

You discover series circuits share one path for all components.

You find parallel circuits give each component its own branch.

You compare voltage, current, and resistance in both circuit types.

What You'll Practice

You will identify series and parallel circuits using key characteristics.

You will explain what happens when one bulb burns out.

You will define circuit terms like voltage, resistance, and conductor.

Why This Matters

Understanding series and parallel circuits helps you explain how electricity powers your home, your devices, and the world around you every single day.
