## Introduction: Chapter 4, Parallel Circuits

In this chapter, we will cover the following:

1. Parallel Circuit Definition

2. Voltage in Parallel Circuit

3. Current in Parallel Circuit

4. Resistance in Parallel Circuit

5. Designing Parallel Circuits

6. Designing Parallel Circuits to Specification

7. Sources in Parallel

8. Current Divider

9. Power Dissipation

10. Differences Between Series and Parallel Circuits

It is imperative that you have a working knowledge of series circuits. If you haven't done so, go over Chapter 3 to learn about series circuits.

## Step 8: Sources in Parallel

One technique to increase current in a circuit is to place power sources in parallel.

Adding another voltage source in parallel to existing voltage sources will not increase total voltage (VT), rather, as stated above it increases the current. To increase total voltage, one must place the additional voltage source in series with the existing voltage source.

Important!
When placing voltage sources in parallel, ensure that all the voltage sources have the same value. If the voltage sources in parallel are not the same value, there is a very high possibility that your voltage source/s will explode.

For example, if V1 = 12V, then V2 and V3 must also be 12V.

## Step 11: Differences Between Series and Parallel Circuit

Dear Geeks,

There will be updates on this chapter (CH 4) to further explain the concepts. So check in every 2 weeks for updates. If you have any comments, suggestions or questions, don't be shy to post.
