### Session Overview

 In this session, we start a new unit on circuits. We will explore different motivations for studying circuits, the conventional representations associated with the study of circuits, and Kirchhoff’s voltage and current laws. The overview handout provides a more detailed introduction, including the big ideas of the session, key vocabulary, what you should understand (theory) and be able to do (practice) after completing this session, and additional resources.

### Session Content

Read sections 6.1-6.5 of the course notes.

#### Lecture Video

Watch the lecture video. The handout and slides present the same material, but the slides include answers to the in-class questions.

Introduction to circuits, including several methods for analyzing circuits (Kirchhoff’s current and voltage laws, node voltages, and loop currents) and common patterns that simplify analysis.

#### Recitation Video

These videos have been developed for OCW Scholar, and are designed to supplement the lecture videos.

### Session Activities

The problems in the tables below are taken from the 6.01 Online Tutor, an interactive environment that is not available on OCW. Do not try to answer these questions in the PDF files; answers will not be checked, and cannot be submitted.
