Electricity - Definition, Examples, Quiz, FAQ, Trivia
Discover how electricity powers our world!
What is Electricity?
Electricity is a form of energy that powers almost everything in our modern world! It's the flow of tiny particles called electrons through materials like wires.
Think of electricity like water flowing through pipes. The voltage is like the water pressure that pushes electrons through wires. The current is the amount of electrons flowing through the wire. And the circuit is the complete path that electricity flows through.
Voltage
The "push" that makes electricity flow
Current
The flow of electrons through a circuit
Circuit
A complete loop for electricity to flow
Electricity Fact!
Electricity travels at nearly the speed of light - about 186,000 miles per second!
Static Electricity
Static electricity is electricity that doesn't move - it stays in one place! It happens when electrons build up on the surface of an object. You've probably experienced static electricity when:
• Your hair stands up after taking off a hat
• You get a shock after walking on carpet
• A balloon sticks to your clothes after rubbing it
Static electricity occurs when two objects rub together and electrons transfer from one object to another. The object that gains electrons becomes negatively charged, while the object that loses electrons becomes positively charged.
Lightning is Static!
Lightning is actually a giant form of static electricity! It happens when electrons build up in clouds and suddenly discharge to the ground.
Simple Circuits
A circuit is a complete path that electricity can flow through. All circuits have three main parts:
Power Source
Provides the energy (like a battery or outlet)
Conductors
Materials that let electricity flow (like wires)
Load
Device that uses the electricity (like a light bulb)
Circuits can be either series circuits (where all components are in one path) or parallel circuits (where components have separate paths).
In a series circuit, if one bulb goes out, they all go out. In a parallel circuit, each bulb has its own path, so if one goes out, the others stay lit!
Electricity in Nature
Electricity isn't just something humans create - it's all around us in nature! Here are some amazing examples:
Lightning
Giant electrical sparks in the atmosphere
Electric Eels
Fish that can generate shocks up to 600 volts!
Nervous System
Your brain uses electricity to send signals
Even our planet has electricity! The Earth's core creates a magnetic field that protects us from solar radiation. This magnetic field is created by electrical currents flowing in the Earth's liquid outer core.

Frequently Asked Questions
Here are answers to common questions about electricity:
Fun Electricity Trivia
Discover some amazing facts about electricity!
Electric Eels
Electric eels can produce shocks of up to 600 volts - enough to stun a horse! They use this ability to navigate, communicate, and hunt.
Lightning Power
A single lightning bolt contains enough electricity to power 200,000 homes! But it only lasts for a fraction of a second.
Body Electricity
Your body generates electricity! Your nervous system uses electrical signals to communicate, and your heart beats because of electrical impulses.
Electric History
The first electric battery was invented in 1800 by Alessandro Volta. We measure voltage in "volts" to honor his discovery!
