Electric Current: Direct Current Circuits

Direct Current Circuits: Introduction

A 9 volt battery.

Circuits are a part of all electronic devices from your television set to your watch. In the last section you learned that current depends on the resistance in the circuit, but what happens if there is more than one resistor? In this section, you will learn how to figure out what happens in a circuit that has multiple resistors in a circuit and how to work with them in series and in parallel.
