The video discusses the risks of using electronic devices in the bathtub and how to minimize them. The host explains that Ground Fault Circuit Interrupter (GFCI) outlets and isolated charger outputs are crucial in preventing electrocution. He demonstrates the effectiveness of GFCI outlets in detecting and shutting off current flow when a live wire comes into contact with water. The host also highlights that some countries may not have strict regulations on electronic devices, leading to the sale of non-isolated chargers and other hazardous products. He advises viewers to avoid using electronic devices in the bathtub, plug them into GFCI outlets, and avoid buying cheap, knockoff electronics. The video is sponsored by Keysight, which is hosting an IoT Innovation Challenge that encourages students to develop solutions for making urban life healthier and keeping waterways clean.
Here are the key facts extracted from the text:
1. The author received a link from his friend about a woman who died after dropping her charging phone into a bathtub.
2. The author has a background in electrical engineering and has experience with electronics.
3. In North America, bathrooms must have GFCI (Ground Fault Circuit Interrupter) outlets.
4. GFCI outlets detect if the current runs between live and earth and shuts down the power if it does.
5. The author demonstrates how GFCI outlets work by connecting a spoon to a live wire and then putting it in a bathtub with water.
6. The author shows that the breaker opens when the spoon is inserted into the water, indicating that the GFCI outlet is working.
7. The author explains that if you drop a hair dryer into a bathtub, it's more dangerous if you try to take it out because the entire current runs through your body.
8. The author advises to always plug electronics into a GFCI outlet and never take live wires into the bathtub.
9. The author explains that phone chargers are isolated from live wires, making it safe to drop a phone into a bathtub while it's charging.
10. The author mentions that in some countries, there may not be regulations on the safety of electronic devices, which can lead to electrocution.
11. The author references a case where a young girl was electrocuted in a bathtub after bypassing the ground fault protection outlet.
12. The author notes that some countries use 220-volt AC, which is more dangerous than the 120-volt AC used in North America.
13. The author warns against buying questionable knockoff electronics and advises to always plug them into a GFCI outlet.
14. The author promotes a competition, the Keysight IOT Innovation Challenge, which aims to tackle real-world problems using IOT solutions.
15. The competition has two challenges: making urban life healthier in big cities and keeping waterways clean.
16. The deadline for the competition is May 15, and the winners will receive cash prizes and equipment for their university.
17. The author offers to give away two handheld Keysight multimeters to his patrons or to those who register from his link.
