When you get an electric shock, it is actually a feeling of high-frequency oscillation. It will stimulate your muscles to contract. So if you get an electric shock on the back of your hand or the outside of your limbs, you will bounce off by your own muscle conditioning. If it's inside, maybe you will catch the power in a conditioned way! This is dangerous!
According to the teacher during the internship, foreign 1 10V alternating current will not kill people in general, provided that the skin is well insulated.
When I was a child, I dismantled an electrical appliance at home to be repaired. As a result, I didn't pull it out, and my finger just bounced off when I touched it. It's like someone hammering your arm with great force, which makes your arm muscles contract. It took a short time and it didn't work.
Then the university used the washing machine in the dormitory, and it still leaked electricity ... There is always a numbness when reaching into the water, just like something is constantly irritating the skin, but the voltage is not high. After a period of use, the washing machine was completely scrapped.
Also, I forgot that the wire of the electrical appliance is broken and there is a little leakage. When you scrape with your arms, you will get a strong electric shock, but it is not as strong as scraping with your fingers directly.
It is probably caused by the instantaneous contraction of our muscles under the action of electric current. We must be careful not to touch high voltage electricity in our daily life, which is very dangerous.
