KNOW WHY CHARGING CABLES ARE SHORT IN LENGTH !

I bet you face the problem of your phone charging cable being short. Have you imagined why mobile manufacturers provide short charging cables? We will explore the reason behind the reason for short cables in this article.

There is science behind the shorter charging cable as companies like Apple and Samsung spent countless hours on their design.Before we go any further we need to establish if the iPhone cable is actually short. So how long is it? The standard cable you receive in your sleek minimalist white box is one metre long.

Following are the reasons why charging cables are short:

1.)Cord length is short is to safeguard us from SAR radiation which smartphone emits while charging. It can be dangerous to talk while charging is on. If the cable is short chances are less that people will use their phone while charging.

2.) The long charging cable will offer more resistance to current. When resistance increases,the current (charging current) decreases.Thus, increase in length of the wire will result in decrease in the charging current, making the charger inefficient.

3.) These cables are kept as short as possible while still being useful. Most smartphone chargers today are designed to be plugged into the USB port of your computer, with the wall adapter as an afterthought, and 6 feet is usually enough to reach the computer sitting on your desk or in your lap. It saves on material and packaging costs, while also avoiding the tangling that long cables are prone to.

4.) They are short because the manufacturer will usually make a longer cord to be purchased separately.


It is highly recommended that you use adapter and charging cable that is compatible with your phone. Changing the compatibility my harm your device and even result in explosion.

KNOW THE FUNCTION OF BUTTON ON THE DOOR HANDLE OF CAR !

You might have seen a small button on the car handle. You might have imagined why this button is for and how it works? We will explore this in this article.

These days a lot of advancement is going on in Automotive field. Every automobile company is developing some technology to make the life of user comfortable.The button that you see on the car handle is known as Request Switch or Request Sensor.This technology allows you to lock and unlock the door just by pressing the Request Switch on the door when you are carrying your key on you. 

You can also open and close the trunk, and can start the engine without having to insert the key, making departure seamless. When you press this button the car sends out a signal searching for the owner, or key fob. When the key fob receives the specific signal, it replies that it is within radius and unlocks the doors for the owner.

Which means you just have to keep  the key in your pocket and press this request switch and you will be able lock and unlock your car door. There is also a same switch at the trunk side.

HOW THIS TECHNOLOGY WORKS:

Intelligent Key utilizes antennae that transmit signals between the car and the key, and a tuner that receives the signals. Pressing the Request Switch transmits a signal from the car antenna, and the key that receives the signal then automatically returns a signal. The car tuner receives this signal and then locks or unlocks the vehicle.

In order to avoid a key being locked up inside the vehicle cabin or trunk, the technology detects the status of the door lock and whether the key is remaining inside the vehicle at the moment when the door or trunk is closed. If it detects that a key has been shut inside the vehicle, it alerts you via a buzzer and simultaneously automatically unlocks the door or opens the trunk.

You can quickly determine if a car has touch-sensitive door locks installed. Take a look at the driver-side door. If no handle or lock are visible, then you can be sure that the car has a touch-sensitive lock installed.

KNOW WHY WHITE PACKETS ARE USED IN NEW PRODUCTS !

We’ve all seen those little white packets that come in the box when we buy a new pair of shoes, a bottle of vitamins, a bag or a new purse. You might be wondering what this white packet is and what is it used for? Let us discuss all these questions in this article.

These little white packets are called silica gel bags. The technical name for it is silica xerogel, but most people just call it silica gel.These bags are filled with a substance called silicon dioxide, a non-toxic inert desiccant that has the power to dry out moisture.Silica, or silicon dioxide (SiO2), is the same material found in quartz. The gel form contains millions of tiny pores that can adsorb and hold moisture. Silica gel is essentially porous sand. Silica gel can adsorb about 40 percent of its weight in moisture and can take the relative humidity in a closed container down to about 40 percent. Once saturated, you can drive the moisture off and reuse silica gel by heating it above 300 degrees F (150 C).

Silica gel packets are used to absorb moisture and keep things dry.

Many manufacturers add these desiccant packs to their new products to keep them fresh and moisture-free for the consumer.In leather products and foods like pepperoni, the lack of moisture can limit the growth of mold and reduce spoilage. In electronics it prevents condensation, which might damage the electronics. If a bottle of vitamins contained any moisture vapor and were cooled rapidly, the condensing moisture would ruin the pills. You will find little silica gel packets in anything that would be affected by excess moisture or condensation.

So, now you know why these packets are used in new products. You also knew how these bags work. Thank you for reading the article.
