Fun Facts

  • Electricity can flow through your body or a pickle!
  • Power grids deliver electricity to our homes.
  • Static electricity and current electricity both exist.

Why Do We Need To Know About Electricity

Learning about electricity helps us understand how many technologies around us work, including things like phones, electric cars, and even space shuttles. Electrical engineers use their skills to create these technologies, making our lives better and easier. They work on cool projects, like making better artificial limbs for people or creating smart skin that can feel.

As electricity and engineering get better, we see big improvements in many areas, including medicine. Knowing how electricity works not only gives you a chance at great jobs but also lets you see how it powers so much of what we use every day, from light switches to computers.

Frequently Asked Questions

What is electricity?
Electricity is the flow of electrical energy from one place to another.
Why is a closed circuit needed for electricity to power our electronics?
For electricity to flow, it needs a closed path from the source, through a conductor, and back to the source.
What would be an advantage of a series circuit? Of a parallel circuit?
In a series circuit, you could turn on and off all the lights or devices at the same time, instead of turning each one on and off separately. In a parallel circuit, each light or device has its own path to the source, so you can control each one separately. If one light or device goes out, the other devices in the circuit are not affected.
