Plasma cutter

The video tutorial explains how to create a small plasma experiment using materials like alligator clips, tin foil, lead, and 9 Volt batteries. It provides a step-by-step guide on setting up the experiment, including connecting the batteries in series and attaching them to the tin foil and lead. The scientific explanation covers how the current flow creates a small plasma ball by vaporizing carbon atoms in the lead and aluminum foil. The tutorial concludes with the expected outcome of the experiment, where both the lead and foil are consumed.

What is the purpose of using a rubber band in the initial setup of the experiment?

• To hold the tin foil in place

• To connect the batteries

• To create a spark

• To insulate the lead

In the experiment, what happens when the lead is brought close to the tin foil?

• The batteries discharge completely

• The tin foil changes color

• A small point of contact is created

• The lead melts

What is the result of the current flowing through the small contact area between the lead and tin foil?

• The area gets extremely hot

• The batteries lose charge

• The lead becomes magnetic

• The tin foil becomes rigid

How are the 9 Volt batteries connected in the final setup?

• In parallel

• Individually

• Randomly

• In series

What is created at the connection point during the experiment?

• A small ball of plasma

• A magnetic field

• A chemical reaction

• A sound wave
