COMO FAZER UM CAPACITOR CASEIRO QUE DÁ CHOQUE

Summary

In this fun and educational video, the creator demonstrates how to make a DIY electric shock cup that doesn’t require batteries or an electrical outlet. Using two cups, aluminum foil, tape, and a bit of creativity, the project involves creating a capacitor. The creator explains the science behind capacitors, showing how they store static electricity. The video includes various methods to charge the cup, such as rubbing it with a balloon, using a PVC pipe, or even an old tube TV. Viewers are shown how the cup can give a harmless shock, and the creator attempts to power a fluorescent lamp using the static electricity.

Takeaways

• 😀 You can make a shocking cup without needing a power outlet, battery, or batteries. It uses static electricity.
• 😀 The project involves using two identical cups that fit into each other.
• 😀 Wrap one of the cups in aluminum foil and secure it with tape to form the base of the capacitor.
• 😀 To create the capacitor, place a small piece of aluminum foil inside the inner cup to act as a connector.
• 😀 Use a balloon to generate static electricity by rubbing it on your hair, then transfer that charge to the capacitor.
• 😀 Static electricity can be used to charge the capacitor, but it requires multiple attempts to build up enough charge.
• 😀 You can also use PVC pipe and paper towels to generate static electricity for charging the cup.
• 😀 Old tube TVs can be used to charge the cup as they become electrically charged when turned on.
• 😀 The shock produced by the cup is not dangerous, but it will give you a small, surprising static shock.
• 😀 The cup can deliver a shock to someone holding it, but there’s no risk of injury.
• 😀 The project also explores using static electricity to light a fluorescent bulb, demonstrating the potential of static charge in a fun and safe way.

Q & A

What materials are needed to create the electric shock cup?

You will need two identical cups, aluminum foil, tape, and an insulating tape. Additionally, a balloon, PVC pipe, or an old tube TV can be used to generate static electricity.

How do the two cups interact in the electric shock cup experiment?

The two cups are placed one inside the other. The outer cup is wrapped in aluminum foil, while a piece of aluminum foil is attached to the inside of the inner cup to create a connection. This forms a simple capacitor.

What role does the aluminum foil play in the experiment?

The aluminum foil serves as one of the metallic plates in the capacitor. It allows the capacitor to store static electricity, which will then be used to generate an electric shock.

What is the purpose of the insulating tape in the experiment?

The insulating tape is used to separate the two cups, preventing unwanted electrical contact between the inner and outer cups. This ensures the correct formation of the capacitor.

What is a capacitor, and how does it work in this experiment?

A capacitor is an electronic component that stores electrical charge. In this experiment, the cups and the aluminum foil create the two metal plates of the capacitor, while the plastic of the cups acts as the insulating material. Static electricity is stored in the capacitor.

How is the capacitor charged in the experiment?

The capacitor is charged using static electricity. You can generate static electricity by rubbing a balloon on your hair, using a PVC pipe, or even using an old tube TV. The static charge is transferred to the aluminum foil to charge the capacitor.

What effect does rubbing a balloon on your hair have on the experiment?

Rubbing a balloon on your hair generates static electricity, which is then transferred to the capacitor. This charge builds up, allowing the cups to store enough energy to deliver a small electric shock.

How can an old tube TV be used to charge the electric shock cup?

An old tube TV can be used because the screen becomes electrically charged when the TV is turned on. You can pass the cups near the front of the screen to transfer static electricity to the aluminum foil and charge the capacitor.

What kind of shock can someone expect from the electric shock cup?

The shock is a mild static electric shock, similar to the small shocks people feel when touching metal objects after walking on a carpet in dry conditions. It’s not dangerous but can startle someone.

Can the electric shock cup be used to light a fluorescent lamp?

Yes, the experimenter tried to light a fluorescent lamp using the static electricity stored in the capacitor. The lamp briefly flickered, showing that the stored charge can be strong enough to cause a visible effect like lighting a lamp.
