Battery

A battery is a small device that stores energy and gives power to things like toys, flashlights, and electronics. It helps them work by sending electricity through a circuit.

I need batteries to make my toy truck move!

Complete Circuit

A complete circuit is a closed loop that allows electricity to flow all the way around. When the path is connected, electricity can flow and power things like a light bulb

Conductors of Electricity

Copper is a good conductor because it lets electricity flow through it easily. That is why many wires are made with copper.

Electrical Charge

I felt a little zap when I touched the door because of static electricity!

Electrical Circuit

An electrical circuit is a path that electricity travels on. It can power things like lights, toys, and devices when the path is complete.

I made an electrical circuit to light up the bulb.

Electrical Current

Electrical current is the movement of electricity as it travels through a circuit, like water flowing through a pipe.

Electrical current is the flow of electricity moving through the wire to make the light bulb glow.

Electrical Insulators

Electrical insulators are materials that block the flow of electricity. They help protect people by keeping electricity inside wires or away from things that could be dangerous.

I want to touch the wire, but the rubber coating keeps me safe because it is an insulator that blocks electricity.

Incomplete Circuits

An incomplete circuit is a broken path where electricity cannot flow all the way through. When a circuit is incomplete, the electrical parts (like a light bulb) will not work because the electricity cannot reach them.

Insulator

An insulator is a material that blocks electricity from flowing through it. Rubber and plastic are insulators that help protect us from electricity.

The wire has an insulator around it to protect people from getting shocked.

Parallel Circuit

A parallel circuit has different paths that electricity can follow. This allows multiple lights or devices to work at the same time.

My house uses a parallel circuit because if one light goes out, the other lights can still stay on.
