I have a question about static electricity. [Copy link]

 

Washing hands can release static electricity from the body, right? So it stands to reason that urinating should also release static electricity, right? Shouldn't static electricity flow out of the body when it touches the ground through water?

Why do I get shocked by static electricity when I wash my hands after urinating every morning and they touch the faucet?

Yes.

Two possibilities:

1. The ground is insulated. The human body is not grounded when urinating.

2. After urinating, you take one or two steps, which generates static electricity.

The toilet cannot be insulated. There is static electricity when walking one or two steps. Is it possible that the static electricity from these one or two steps is enough to shock people? ?

It's entirely possible.

In winter, the climate is dry, and the heavy clothes and friction from walking cause the Tesla coil tip to discharge all the time at night.

The question is how to transfer the charge on your hand to certain parts. After all, the human body also has resistance.

The generation of static electricity is very random, and it may be caused by inadvertent friction.

When you urinate, static electricity is released in some places.

Some places have not been released yet.

Especially on sweaters and other clothes. Sometimes sparks will appear when you touch them.

It's a strange question. Is this a situation where you are electrocuted every day?

Will the faucet have static electricity? [Reverse consideration], there was a 220V leakage at the workstation before, and I would be hit by static electricity every time I touched the workstation. Later, I accidentally discovered that the 220V electricity was induced to the workstation for some reason, causing me to be hit by static electricity every day. Later, I re-laid the 220V line and there was no problem.

When you urinate, the water falls down at an accelerated speed. At this time, the water column looks continuous, but it is actually a series of water drops, and the distance between the water drops is discontinuous. If the guess is correct, you can verify it through an experiment. That is, use a piece of wire when you urinate, and then connect it to see if there is electricity. Another possibility is that the potential of the pool is almost the same as yours.

Whether the static electricity has not been discharged or new static electricity has been generated needs to be determined experimentally.

First, drink a lot of water. After a suitable period of time, turn up the bathroom temperature to make the air as dry as possible. Then, wear appropriate clothing or use an electrostatic generator to charge yourself with enough static electricity to be easily observed or felt, and verify that you are indeed reliably charged.

If you urinate after being charged and then touch the faucet, and there is still static electricity discharge, it means that there is a problem in the discharge link.

It is recommended to repeat the experiment by repeatedly controlling the urine volume, force, angle and other parameters, carefully observing the relationship between discharge and "discharge operation" and summarizing the rules. If there is a high-speed camera, filming and observation will be more accurate.

For auxiliary experiments, wear the clothes mentioned in the original poster's post, first discharge the electricity reliably, then simulate the movements and behaviors after "discharge", and then test whether the discharge phenomenon will occur again.

It's strange, I get up in the morning, put on two clothes, and do it once a day

I haven't thought about this question, but where is the static electricity in the body stored?

Yes, now I get shocked once every morning, but not at other times. It's been about a month now. I get shocked every morning when I touch the faucet. Now I don't dare to touch the faucet. After the shock once, I'm fine when I touch the faucet again throughout the day.

No, there are no electrical wires or appliances within 2 meters of the faucet.

This is unlikely. I feel like it is conductive. And I'm also curious, why doesn't static electricity shock people when they discharge electricity in a certain part of their body during urination?

This step is indeed rigorous

Is it necessary to be so rigorous? Do I need to connect a multimeter to a special part and measure the ground?
