We use electricity in many ways every day. When the power goes out, you notice it because the machines and devices that you rely on stop working. An electrical engineer is a person who helps to create and improve things that run on electricity. But exactly what is electricity, and how does it work?
What Is Electricity?
Electricity is a powerful force that we find in nature. It all starts with atoms, tiny things that make everything around us. Atoms contain protons and neutrons, which make up the center of each atom, and they also contain electrons, which are particles that move around the outside of the atom. The electrons are always moving and can jump from one atom to the next, and it’s those moving electrons that make up the electricity we use every day.

How Was Electricity Discovered?
A few different people played a role in the discovery of electricity, but the most famous one is Benjamin Franklin. In the 1700s, he performed many experiments to prove that lightning had an electrical charge and this electricity could be captured. One particular stormy evening, he decided to fly a kite with a metal key attached to the string. The key attracted electrons, which traveled into a special jar attached to the string. It was a turning point in electrical history, but harnessing that energy for use came from other inventors later on, such as Thomas Edison, who invented the light bulb.

How Do We Get Electricity?
Electric companies use power stations that generate energy. The energy travels through power lines to a substation and then through more power lines to your home. Each house has an electrical meter. The electricity moves through the meter and into your home’s electrical panel to be sent throughout your house. The electric company can make electricity using energy from many different sources, including things like the sun and wind.

Electricity is very useful, but it can also be dangerous. People can get seriously hurt if they come into contact with an electrical charge, so it’s important that we learn how to use electricity properly. One thing we should always remember is to never touch a power line. A lot of volts of electricity travel through those lines. If a power line goes down, call the power company and let their engineer handle it: Never touch it yourself. Another good safety rule to remember is to keep electrical appliances and devices away from water, as the electricity can travel through the water and hurt someone.
