It's winter

Besides being frozen and shivering

The most annoying thing is probably static electricity

 

After moving bricks and going home, touching the doorknob,Snap

Wash hands to prevent COVID, turn on the faucet,Snap

Ask the male and female gods out, the opportunity has come,Snap

Electrified to the point of questioning life...

 

To avoid being shocked, many friends have also bought

Anti-static wristbands, anti-static sprays, and other products

But the effects are mediocre, you still get shocked if you are going to be shocked

 

As the saying goes, know yourself and know your enemy, and you can win a hundred battles

Similarly, to thoroughly understand static electricity, you can counter it!

 

 

Everyone knows that batteries havePositive terminal (+)andNegative terminal (-)

And the countless atoms that make up our bodies

Also consist of atoms that carry

Positive chargeNucleus (+)andNegative chargeElectrons (-)

 

In an ideal situation

Positive and negative charges are equal and cancel each other out

At this time, we will not generate static electricity

But the problem isElectronsThis guy

Is a particularly mischievous little rascal

Likes to jump around for no reason

Sometimes even goes off track and runs to other places

 

When we have close contact with clothes and shoes

Electrons will enter party mode

Wandering between us and our clothes

The different materials of the clothes determine

Whether the electrons move from us to the clothes or from the clothes to us

 

This leads to the fact that we have

Positive charge (+) ≠ Negative charge (-)

Static electricity will secretly start to occupy your body

        

PS: This is an example to illustrate positive charge

Static electricity can be either positive or negative

In fact, when the air is relatively humid

These charges on the body canBe "relatively gentle"And

Will be conducted away by the air little by little

Static electricity will naturally be expelled from the body

But once it reaches the dry winter

The moisture in the air is greatly reduced

The electricity on the body is difficult to "conduct" away

 

And the weather is cold

You won't just run around barefoot at home

Generally, shoe materials are non-conductive

So you can't discharge static electricity through your feet

 

 

There’s no way to conduct away these charges

Static electricity will accumulate more and more on us

 

 

We, filled with static electricity

If we happen to touch highly conductive

Metal products like doorknobs, faucets, etc.

Static electricity will be conducted away in an instant

Instantly generating extremely high voltage

A tragedy happens...

 

Although this amount of electricity is small and won't kill anyone

ButThe voltage can instantly reach tens of thousands of volts!

The household AC is only 220 volts

That's why it hurts so much...

 

 

So the first trick to combat static electricity is

Not to let static electricity accumulate too much

 

Use fabric softener when doing laundry

Or wear more cotton clothes

This can reduce the generation of static electricity

 

Additionally, you can use a humidifier

To increase the humidity of the air

Or occasionally touch the wall, touch the ground

To discharge static electricity, preventing it from "gathering to cause trouble"

However...

Humidifiers can't be used everywhere

Constantly touching walls and floors isn't very hygienic

Practicality is discounted

 

Let me introduce a method that has been tested and proven effective

After using it, the number of times I got shocked decreased significantly

Occasionally I still get shocked, but it’s not that painful.

If it doesn't work, come find me

 

Then it is

Before touching high-risk objects like door handles

Use the key you carry with you to poke the door handle first

This way, the one getting shocked first is the key, not you...

But there are three points to note

 

First, the key must be carried with you

This way, you and the key will have the same potential

 

Second, the key must be metal

Of course, other metal objects are also acceptable

The important thing is that the material can conduct electricity

 

Third, remember to hold the metal part

Now many keys have plastic handles

If you hold the plastic handle, static electricity cannot be discharged in advance

 

What? Can't remember?

Just get shocked a few more times

Guarantee you'll remember that winter

Or review the article a few more times

But those who often walk by the river will inevitably get their shoes wet

What if you encounter a situation where you can only go head-to-head?

What should you do?

Then please boldly use your large palm to grasp it!

The closer, the better!

If you chicken out

Frantically test with your fingertips

You will only get shocked even more painfully

 

This may be a bit counterintuitive, unbelievable

But this is scientifically based

The moment we get shocked by static electricity when opening the door

Our hand and the door handle

Form a structure similar to a capacitor

Thus generating voltage and current

And how painful it is to get shocked

Depends on how high the voltage is

Let's go straight to the formula

We canIncrease capacitance to reduce voltage

And the most convenient way to increase capacitance

Is toIncrease the contact area with the door handle

Use a larger palm to touch the door handle

Instead of your fingertips

 

This way, the voltage when getting shocked will be a little lower

It won't hurt as much!

So don't be afraid, don't chicken out

When there are no other options

Courage will lessen your pain

Although static electricity is indeed annoying

But what people may not know is

The phenomenon of static electricity has been widely applied in our

Daily life and industrial production

For example, the photocopiers we often use

Utilize the characteristics of static electricity

To allow toner to adhere to designated positions

Thus forming the shapes or text that need to be printed

 

Similarly, small static electricity is also applied to

Artificial rainfall, artificial pollination, agricultural selection

Desalination, oil dehydration, dust prevention, spraying

And other fields

Disaster is where fortune lies

As long as you have a curious heart

You can also let the static electricity that we both hate and fear

Benefit our lives
