How electrons work?

Electrons have negative charges, and unlike neutrons and protons are located on the outside of the atom. They are generally located in electron clouds around the atom, and stay there because of their attraction to protons that are in the nucleus of the atom.

Difference between tunnel diode and PN junction diode?

there is difference between doping levels.In normal PN junction diode we add 1 impurity for 108 atoms where as in tunnel diode we add 1 impurity for 103 atoms.there is a probability that electrons may penetrate through barrier.So will not disappear

in tunnel diode we get maximum current before barrier disappear where as we get maximum current after break down(there is no barrier)

this effect lies within a certain voltage limit of 0.4V.

When we consider the energy band structure in case of PN junction diode the fermi level lies inside the forbidden energy gap.In case of tunnel diode,the fermi level lies outside the forbidden energy band.

In tunnel diode, there is a topic about negative resistance region where as we cannot discuss it in PN junction diode.

ur friend,

uma.

What is the brightest light emitting diode?

L.E.D or light emitting diode A light-emitting diode (LED) is a semiconductor light source.[3] LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Introduced as a practical electronic component in 1962,[4] early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness

What is an electronic device?

a number of kit-type electronic devices such as radio transmitter sets- like one by GE If I remember correctly, were marketed in transparent cases, so on display all the major components of the set- tubes, transistors, capacitors, relays, etc would be clearly visible and usually a circuit diagram was printed on the breadboard of the assembly- do not confuse with printed circuits- this is more like a map or assembly diagram. They were clearly angled at the youth and especially the Science-Fair market.

What is break down region of zener diode?

Zener breakdown is the phenomena wherein the Zener diode experiences reverse breakdown at a much lower voltage than a normal diode, which may breakdown in excess of 100 volts, depending on the type. This is useful because the Zener will hold the same voltage after breakdown, regardless of the input voltage, making them excellent for voltage controlled switches and references.

Show the data processing cycle?

The data processing cycle is the process of converting data into useful information.

The data is processed again and again until the accurate result is achieved.

The three basic activities of data processing are:

1. Input

2. Processing

3. Output

Do you have to charge a new stun gun?

Check the instructions that come with the stun gun. Most stun guns do require charging for the first time.

What will happen to an ammeter reading if the resistors are connected in parallel?

You would be drawing more current. It would be the same as adding more load to the circuit in a vehicle, say more lights. The lights would just be seen as more load (a resistive load in the case of incandescent lights). Add more lights (resistors) and more current is needed. The ammeter would indicate a higher current draw.

Who invented the taser?

The Taser was invented by Jack Cover in the late 1960s. Cover was a NASA researcher who was interested in finding a non-lethal way to stop suspects without using firearms. He named his device the Taser, which stands for "Thomas A. Swift's Electric Rifle," after a character in a series of adventure novels. The first Taser was developed in 1969 and was initially used by law enforcement agencies in the 1970s. Since then, Tasers have become a common non-lethal weapon used by police and military forces around the world.

Distinguish between open and closed systems?

Open systems are systems where items are free to enter and exit as they please such as Earth and the universe. Closed systems are contained such as that of a plant organism.

Are lithium batteries better than nickel metal hydride batteries?

Yes because they use less chemicals, last longer per charge and last through more charges

lithium batteries are non rechargeable. Lithium ion batteries are rechargeable.

lithium batteries last a lot longer than standard alkaline batteries and work well in digital cameras and stuff that are high drain.

NiMH is also good for the same purpose.

it depends on your preference. if you dont mind charging the batteries multiple times than go with NiMH. if you want to use something for a good while and throw them away, use lithium. both have their pros and cons.

Which is better phones or smartwatch?

Both have their ups and downs. Phones allow you to put them wherever you please as with watches, they have to be put on your wrist. On the other hand, smart watches allow you to see calls easier and answer them quicker.

Which are good led TV manufacturers in India?

Blueberry can help you. They are led tv manufacturers and dealers.

How can i start making money online but have no resources?

You can see there are hundreds of websites already offering quick ways to make money. But you have to be careful before getting into any program, pick the genuine and legitimate ways to make money online.

What is a license key and a license name?

A license key and a license name are two different things. A license key is a specific code that unlocks a particular program, allowing users to access its features. For example, software programs will typically require a license key in order to be used**.** A license name is a unique identifier associated with a particular license key. It is a way of distinguishing between different licenses and can be used to track who is using a particular key.

Microprokey. com is one of the best websites for obtaining license keys and names. They provide a wide range of products, including licenses for software programs, games, and operating systems. They also offer a variety of payment options, including credit cards, PayPal, Once a license is purchased, a license key and license name will be provided. These can then be used to activate the program and access its features.

How do you stabilize an amplifier?

One method is by adding negative feedback from the output to the input stages.

What is the difference between mama and baba?

In Hungarian-American families, baba is like saying "grandmother". Some may use it instead of "grandmother" in reference to a great-grandmother. Mama means just that; your maternal parent.

Who invented the father radio?

Nikola Tesla. Though credit is often attributed to Marconi, due to his transatlantic broadcast, Tesla had working wireless devices more than a decade before.

How do you send a digital radio signal to a FM radio?

Frequency Modulation must have a carrier whereby the frequency can be modulated by the signal
