Question

what is the substance material that flows down in the illustration above and how can compare it to electricity​

Answer 1

Answer:

The flow of electricity is called current. Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.

Answer 2

Electricity powers many of the devices you use every day. Those devices are made up of circuits, ranging from very simple (such as a lamp with a single lightbulb) to very complex (such as in a computer). Try this project to build your own simple circuit and use it to test which common household materials conduct electricity
