Electrical Systems

They are all examples of electrical systems that play a significant part in our daily lives.
Since the late 19th century, electricity became more commercially available to the general public, allowing inventors and engineers to build electricity-dependent machines that we could use in our homes.

How do electrical systems work?

In this electrical system, the switch is open, or in the OFF position. Electricity in not being conducted around the circuit.

Now the switch is closed, and in the ON position. This is what happens when you turn something ‘on’ at home.

How would conductors and insulators be useful in my electrical system?

Some materials allow electricity to easily pass through. These are called conductors.

Selecting these materials in your design will give your product some functionality.

Target audience—Who are you designing for?

Switch = OPEN

Switch = CLOSED

Key Inventor

Some materials prevent electricity from passing through them and are called insulators.

Selecting these materials in your design will give your product safety.

Thomas Edison

Thomas Edison was an American inventor who transformed the world with his invention of the lightbulb. He invented a carbon filament that burned for 40 hours, the first practical lightbulb! Billions are in use around the world today.
