Have you ever thought about what life would be like without electricity? It’s hard to imagine, right? We use electricity every day, whether it’s turning on the TV, listening to music with headphones, or making toast for breakfast.
Electricity is a special kind of energy that comes from something called an electric charge. When this charge moves, it creates energy that powers all sorts of devices. Sometimes, we get electricity by plugging things into the wall, which connects to power lines. Other times, we use batteries that store energy until they run out.
For things like games, computers, and toys to work, they need to be part of a circuit. A circuit is like a big loop that electricity travels through. If the loop is complete, electricity can flow and make things work.
Think of riding a bike. You need to keep pedaling to move forward because the chain spins the wheels. If the chain breaks, the bike stops. A circuit works the same way. If there’s a break in the loop, electricity can’t flow, and the device stops working.
Let’s see how a lightbulb turns on. When you plug it in, electricity flows through the circuit, lighting up the bulb. But if any part of the circuit is broken, the electricity can’t flow, and the light goes out.
Switches work by opening and closing circuits. When you flip a switch on, the circuit closes, and electricity flows to turn on the light. When you turn the switch off, the circuit opens, stopping the electricity and turning off the light.
Electricity is powerful and can be dangerous, so it’s important to stay safe. Electricity travels easily through materials called conductors. Metal is a good conductor because electricity moves through it quickly.
Since electricity moves through conductors, it’s dangerous to touch metal parts when using an appliance. Water is also a good conductor, so it’s important to keep electrical devices away from water.
To protect ourselves, we use insulators. Insulators are materials that electricity can’t travel through easily, making them safe to touch. Rubber is a great insulator, which is why power cords are often coated in rubber. This keeps the electricity inside the cord and prevents accidents.
Electricity is everywhere and helps us do many things, from staying warm to having fun. But remember, there are lots of ways to enjoy life without electricity, too. Whether you’re playing outside or reading a book, there’s always something fun to do!

[Voiceover] It can be difficult to imagine life without electricity, can’t it? We find ourselves surrounded by electricity every day. Every time you switch on your TV, listen to your headphones, or use a toaster, you use electricity.
Electricity is a force caused by an electric charge. When the charge moves, it provides a form of energy that we can use to power devices and make them work. Sometimes, you access electricity by plugging an appliance into your wall and using the electricity from power lines. Other times, you use batteries that store energy for you to use until they run out.
For your games, computers, and toys that require electricity to work, they need to be part of a circuit. A circuit is like a big electrical loop. In order for the circuit to work, the whole loop must be complete.
Imagine you are riding your bike. To move forward, you need to continue pedaling so that the chains keep spinning your wheels. Now just imagine that this chain is broken. The bike would stop moving. This is a bit like how a circuit works.
Let’s look at the circuit needed to turn a lightbulb on. Once plugged in, a current flow pushes an electrical charge around the circuit, activating the lightbulb. But if any part of the circuit is broken, the electrical charges cannot flow through the circuit, and the light would stop working.
This is also what happens when you use a switch. In this circuit, you can plug it in and turn the switch on. The current of the electric charge will turn the lightbulb on. But when you turn the switch off, the circuit is open, which turns the lightbulb off. A circuit needs to be complete for electricity to work in an appliance.
Electricity can be very dangerous, so it’s helpful to know how to protect ourselves while using it. Electricity travels through materials that are easy to flow through, called conductors. Metal is a good conductor because the electrical charges move through it very fast.
Because electricity moves through conductors, it’s very dangerous to touch any metal parts while an appliance is being used. Water also conducts electricity very easily, making it dangerous to bring electrical equipment near water.
We protect ourselves from electricity by using insulators. Insulators are materials that do not conduct electricity and are safe to touch. Rubber, for example, is a good insulator. We use rubber coatings around power cords as an insulator because it stops the electricity from escaping, which prevents you from being electrocuted.
Electricity is everywhere and helps us to do many things for survival and enjoyment. But it’s also important to remember that although electricity can power many exciting devices, there are many other ways we can have fun unplugged.
