## Introduction

In this experiment, we will be testing tesla and determining the difference in the flow of electricity in the open air and in the vacuum. We will check how electricity flows through different atmospheres: an open air, an empty vacuum, one filled with helium, and one filled with argon.

## Aim

To determine the flow of electricity through different mediums, including open-air, empty vacuum, one filled with helium, and one filled with argon.

## Theory

1. Tesla coil is used for generating very high voltage, which can go more than a million volts.

2. Tesla coils transmit electricity through the air.

3. It creates an electric field that transmits electrons through the light bulb.

Tesla Coil

## Requirements

1. Tesla coil,

2. 6-volt batteries (lantern batteries),

3. Solid core hookup wire,

4. Knife switch with screw connectors,

5. 12-volt relay switch with soldering connectors,

6. 12-volt automotive ignition coil,

7. Soldering wire,

8. Soldering tools,

9. Alligator clips,

10. Mounting board,

11. Vacuum tube,

12. 6 in long by 3 in diameter clear plastic tube,

13. Vacuum pump,

14. Copper tubing,

15. Various sealing valves,

16. Argon,

17. Helium.

## Procedure

Step 1: Bring the objects one by one in contact with the tesla coil.

Step 2: Perform this experiment in three types of chambers, a vacuum chamber, one filled with helium and argon, and one in the open air.

Step 3: Record your observations.

## Observation

1. We observed that electricity changes its colour in different atmospheres, and the distance covered by it in a vacuum is much greater than that in the open air.

2. Results for electricity flow through helium and argon are still pending.

## Result

1. Due to the lack of molecules, electricity flows much farther in a vacuum than that in the open air because molecules restrict electric flow.

2. In the open air, the presence of molecules makes it difficult for electricity to travel greater distances.

## Precautions

1. Record your observation carefully,

2. Use a Tesla coil carefully to avoid any danger.

## Conclusion

In this experiment, using a tesla coil we tested electrical flow in a vacuum chamber, in an open-air chamber, and in one that was filled with helium and argon.

## VIVA Questions With Answers

Q.1 What was the aim of your experiment?

ANS. To determine the flow of electricity through different mediums that include open-air, empty vacuum, one filled with helium, and one filled with argon.

Q.2 What do you understand about the Tesla coil?

ANS. Tesla coil is used for generating very high voltage, which can go more than a million volts.

Q.3 What is the difference between a Tesla coil and a Van de Graff generator?

ANS. In a Van de Graff generator, static electricity is being generated i.e., charges can not move on their own while in a tesla coil, current electricity is being generated i.e., charges move on their own.

Q.4 What is the result of your experiment?

ANS. Electricity changes its colour in different atmospheres, and the distance covered by it in a vacuum is much greater than that in the open air.

Q.5 Why does electricity cover a greater distance in the vacuum than that in the air?

ANS. Due to the lack of molecules, electricity flows much farther in the vacuum than that in the open air because molecules restrict electric flow.
