Pros and Cons of Electronic Devices for Kids?
Children today are both blessed and cursed to have access to a world of infinite information. This world, known as the Internet, can be used for anything imaginable, from teaching children the sounds letters make, to learning all about dinosaurs or rocket ships. This all comes with a price however, and many parents are left wondering if allowing their children to constantly play with electronic devices is the best thing for them.
On the one hand, electronic devices are great for several reasons. For example, a parent may not be able to take their child to the library as often as they'd like, but with the Internet, there are dozens of websites that can read a wide range of books to your child. Some sites, such as YouTube, even illustrate the pictures, allowing the book to literally come alive.
Children also tend to change their mind about what they love and hate. One day your daughter may love dinosaurs, but the next day she's only interested in princesses. With the Internet, it doesn't matter what her obsession of the day is, you can use these electronic devices to keep her entertained. In a few clicks of a mouse, you can print out a new princess coloring book for her to color, or even stream the latest fairy tale movie.
On the other hand, electronic devices are fragile, especially for young children. Humans today live in a world of iPads, iPhones, laptops and netbooks, and these devices are only getting smaller. All it takes is one drop or one spilled drink and these devices are destroyed forever. With children, these accidents are bound to happen at least sometimes.
Electronic devices can also be addictive, and not everyone who uses them is nice. For these reasons, it's highly recommended that parents limit 'screen time' to only an hour or two a day, depending on the age of the child. Children should also be taught Internet safety from a young age. This includes never telling anyone their real name, where they live, and absolutely no meeting up with strangers, no matter how well you think you know them. If a child is too young to understand these rules, parental control programs can be installed on the electronic devices to insure maximum protection.
What are the Elements of optical fiber communication link?
If light meets the inner surface of the cladding (the core - cladding interface) at greater than or equal to Qc then TIR occurs. So all the energy in the ray of light is reflected back into the core and none escapes into the cladding. The ray then crosses to the other side of the core and, because the fiber is more or less straight , the ray will meet the cladding on the other side at an angle which again causes TIR. The ray is then reflected back across the core again and the same thing happens. In this way the light zig zags its way along the fiber. This means that the light will be transmitted to the end of the fiber.
In reality the light which enters the fiber is a focused beam, consisting of many millions of "rays" behaving in a similar way. They all zig zag along the core of the fiber, crossing over each other, and filling up the core with light. A pulse of light traveling along the core of the fiber is really a bundle of these rays.

What is the full form of cern?
CERN stands for Conseil Européen pour la Recherche Nucléaire, which is French for "European Organization for Nuclear Research".
Since the foundation of CERN the official name was changed into "Organisation Européenne pour la Recherche Nucléaire"
What is a fully automated home called?
A "smart home" refers to a residence that is equipped with devices and systems that can be remotely controlled and automated. These devices are connected to a central hub or network, allowing homeowners to manage and control various aspects of their home through a smartphone, tablet, or voice commands.
A smart home typically includes a variety of features and functionalities that enhance convenience, comfort, security, and energy efficiency. Some common components of a smart home include:
-
Smart Security: Smart security systems provide enhanced surveillance and protection. These may include smart door locks, security cameras, motion sensors, and alarm systems that can be controlled and monitored remotely.
-
Ambience Control: Smart homes often include technology that allows homeowners to control lighting, temperature, and other environmental factors. This can be done through smart bulbs, smart thermostats, and smart switches, allowing for personalized settings and energy savings.
-
Scene Control: With scene control, homeowners can create pre-set scenes or scenarios that automate various aspects of their home. For example, a "movie night" scene could dim the lights, lower the blinds, and turn on the TV and audio system with a single command or button press.
-
Curtain Control: Smart curtain systems enable automated control of curtains or blinds, allowing homeowners to adjust privacy, sunlight, and temperature with ease.
Before the advent of modern smart home technology, there were examples of homes that incorporated some elements of automation and remote control. However, these early systems were limited in scope and functionality compared to today's smart homes.
One notable example is the "X10" technology, introduced in the 1970s. X10 used electrical wiring to transmit signals and control devices like lights and appliances. Although it had limitations and reliability issues, it laid the foundation for future advancements in home automation.
Another example is the "Clapper," a sound-activated device introduced in the 1980s that allowed users to control lights and appliances by clapping their hands. While simplistic in comparison to modern smart home systems, it showcased the concept of remote control and automation.
Overall, while elements of automation and remote control existed before the technology behind smart homes was fully developed, the scope and capabilities of these early systems were far more limited compared to the sophisticated, interconnected, and feature-rich smart homes we have today.
How does e-waste affect the atmosphere?
e waste affects the atmosphere because it cause polution into the air and kills animals people and the environment
Who is the father of electronics communication?
For wireless communication, undoubtedly Guglielmo Marconi, who invented the spark gap transmitter. Then for telegraphy, it has to be Samuel Morse. The telephone was invented by Alexander Graham Bell.
Why resistor is an electronic device?
electronic circuits are those which deals with flow of electrons. in general electronic devices are categorized based on the flow of e as conductor, insulator and semiconductor. since resistor resists the flow of electrons (it deals or works with electrons), it is consider as an electronic device.
Can you use a12vdc 2000ma power supply to power a 12vdc 1000ma device safely?
Depending on what type of power supply it is there are a few options.
If the 2000mA rating means it'll supply up to 2000mA, you're already okay, although you should put a resistor in parallel with the device to safely dissipate extra power. You wouldn't want to exactly split the supply in case the device has current demand variations. It would probably be best to siphon off say, 750mA. Since it's 12 volts, from ohm's law: V = IR you'd want 12 = 750mA*R, or a 16 Ohm resistor. It would also have to handle the power output, where P = IV, so P = 12v*750mA = 9 W. This is a lot of power, but you could probably find such a resistor somewhere. (Try looking at sandstone power resistors)
However, if the supply is powering a sealed device (eg something you wouldn't open up and tamper with), I think you'd be better off just finding the appropriate power supply.
- bipolar devices use both majority and minority current carriers
- unipolar devices use only majority current carriers
What are the differences between electronics and photonics?
I think you mean proton and electron...The main difference is charge. Protons are positive and electrons are negative. The mass of both protons and electrons are almost exactly the same. The size of electrons are slightly smaller than that of protons.
There could be many different causes of overloading any motor.
Here is a short list to get you started:
- the motor's rotor bearings are seizing-up due to mechanical damage or lack of grease or oil
- the load machinery or equipment which the motor is intended to drive has moving parts which are seizing-up due to mechanical damage or lack of grease or oil
- more output power is being demanded of the motor than it was designed to supply - for instance too big a load of clothes has been put into the drum of a washing machine...
The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages.

What happens when resistors are interconnected in a circuit?
The net resistance can be found out using the algebraic sums f series and parallel connections. When there is no current flowing in the circuit the net resistance is infinite.
Is electronics and communication and electronics and telecommunication the same?
Electronics and communication and electronics and telecommunication are same but they have little difference. Electronics and communication deals with all type of communication technologies while the Telecommunication branch deals with only telecommunication those are-
Telephony
Telegraphy.
What VCC stands for in electronics?
Addition:
VCC, VEE, VBB are grounded voltages of a collector, emitter, and base, respectively, on a transistor.
The reason this letter is doubled is to represent a voltage connected between ground and the collector(/emitter/base). Since there is no notation to identify ground (0), the corresponding letter is doubled (IEEE standard). One way to read this notation is as the 'grounded voltage of the collector/emitter/base."
Answer
The representations like Vcc ,Vbb , Vee etc are just a part a nomenclature.
it is used to represent the voltage given to the nodes of the transistor
in this nomenclature voltage given to the ends are denoted by the letter v for the supply voltage and 2 times the first letter of emitter collector or the base where the voltage is given
What are the application of voltage shunt amplifier?
Applications of Voltage shunt feedback amplifier?
What is the effects of more than one voltage source in a network?
Two voltage sources in series can either add up or cancel out depending on which way round they are orientated. If the two positive or the two negative terminals are connected together, the overall voltage is the subtraction of the two. If the positive terminal from one supply is connected to the negative terminal from another, the overall voltage is the sum of the two.
What is the purpose of a capacitor in a circuit?
To store energy, in an electric field between separated charges.
(An inductor stores energy in a magnetic field surrounding a current.)
What is the difference between variable transformer and ordinary transformer?
Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.
