# Physics Tutorial 14.1 - Electric Charges. Conductors and Insulators

There are 8 lessons in this physics tutorial covering Electric Charges. Conductors and Insulators. The tutorial starts with an introduction to Electric Charges. Conductors and Insulators and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of Electric Charges. Conductors and Insulators. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

• What are electric charges?
• How do the electric charges behave?
• What is the unit of electric charge?
• What is an elementary electric charge?
• What is static electricity?
• What are electric conductors and insulators?
• How do we charge objects electrically?
• What is the charge distribution in objects?
• What is lightning? How can we protect ourselves from it?
• What is grounding process and why is it so useful in daily life?
• What is an electroscope and how can we charge or discharge it?
• What are some applications of electrostatics in daily life?

## Introduction

Try to complete the following activities at home:

1. Cut a sheet of paper in very small pieces and put them on a table. Then, take a plastic ruler and rub it several times with you hair. Then, move the ruler close to the small paper pieces. What do you see?
2. Repeat the same experiment but this time by rubbing an air balloon with a woollen cloth. What do you see?
3. If possible, slide down through a playground slide and immediately touch a metal object, for example, the slide holders. What do you feel?

If you cannot do these activities, don't worry. We will tell you what happens in each case. Thus, in the first and the second case, the ruler and balloon will attract the small pieces of paper, while in the third case you will get a slight electric shock when touching the metal object.

All these examples are demonstrations of the electric nature of matter, for which we will discuss in this tutorial.
