**Understanding series and parallel circuits** is crucial for mastering electrical concepts in physics. This guide covers key components like **current**, **voltage**, and **resistance**, explaining how they behave differently in series and parallel configurations. Students will learn about circuit diagrams, calculations, and practical applications of these fundamental principles.

• **Series circuits** have components connected in a single loop, where current is constant but voltage is divided.

• **Parallel circuits** feature multiple loops, with voltage remaining constant across components while current is split.

• The guide explains how to calculate total resistance in both types of circuits.

• Key circuit symbols and their meanings are provided for better comprehension of circuit diagrams.
