**Title:** Debunking Exaggerated Voltage Claims in Stun Guns
**Summary:**
* The creator critiques the "Yellow Jacket" stun gun phone case, claiming 7 million volts, and similar products with inflated voltage claims.
* They explain that voltage is limited by air breakdown (around 15,000-30,000 volts per cm) and demonstrate this using an ESD gun.
* To achieve extremely high voltages (e.g., 7 million volts), impractically large distances between electrodes would be required (e.g., >3.5 meters).
* The creator also corrects a common misconception: "it's not the voltage, it's the current" that hurts, emphasizing that high voltage across the body can lead to lethal currents.
* Examples of misleading marketing and a critique of a Van de Graaff tower demonstration are also discussed, highlighting the importance of understanding electrical principles to avoid misinformation.
Here are the key facts extracted from the text, excluding opinions:
**Electronics and Physics**
1. **Voltage Definition**: Voltage is the electromotive force or potential energy required to move an electrical charge.
2. **Unit of Voltage**: The unit of voltage is Volt (V).
3. **Air Breakdown Voltage**: Air can break down under 15,000 to 30,000 volts across a one-centimeter gap, depending on humidity and pressure.
4. **Arc Formation**: Ionized air between two points with a voltage difference can lead to an electrical arc.
5. **Current and Voltage Relationship**: If a supply is current-limited, the voltage must drop to maintain the set current.
**Products and Claims**
6. **Yellow Jacket Stun Gun**: A cell phone case claiming to output 7 million volts of stun gun protection.
7. **Other Stun Gun Claims**: Various products claim high voltages, including 6 million volts, 18 million volts, and 980 million volts.
**Legality**
8. **Stun Gun Legality in Canada**: Tasers are considered prohibited weapons in Canada.
9. **Stun Gun Legality in the US**: Tasers are not considered firearms in the United States.
**Miscellaneous**
10. **JerryRigEverything**: A channel run by Zack Nelson, who has a bachelor's degree in management, not electronics.
11. **Van de Graaff Tower Experiment**: Touching a Van de Graaff tower can cause hair to stand up due to static electricity.
12. **Effect of Electrical Shock on Humans**: High voltage across the body can lead to severe harm or death due to uncontrolled current flow.
