Why copper wire is more elastic than rubber?
because copper is a metal and polthene is a non metal? Infact, polythene doesn't even conduct electricity....
What are the advantages of AC and DC electricity?
AC electricity will not dissipate in charge traveling along a wire for up to hundreds of miles whereas DC dissapates at about 2 miles at its best. DC is simple and easy, the simplist electrical cirtuit possable.
What metal is number one in electrical conductivity and heat?
Silver is the best conductor of both electricity and heat among metals due to its high density of free electrons, which allows for easy movement of charge and thermal energy. Copper also has excellent conductivity properties and is commonly used in electrical wiring and heat exchangers.
Does silk conduct electricity?
Usually not. But there's a lot of stuff behind that idea. Grab a seat and lend an ear. We'll walk through it. If you take a silk cloth and rub it on, say, a balloon, a form of what is called contact electrification will take place. It's sometimes called triboelectric effect, and you know it as static electricity. The friction causes electrical charges to move, and they will separate in this case because the silk cloth and the balloon are not generally good conductors. In contrast, if you rubbed a metal rod with a silk scarf, you could rub all day and not significantly separate any charges. That's because the metal conducts the charges to permit them to "get back where they came from" so no static charge can build up. Not a difficult idea to understand, is it? Nope. But let's get personal. You walk across a rug on a warm, dry day and reach out for the door knob. Zap! You were just electrocuted by a few thousand volts (but very little current). The friction of your movement across the rug separated charges, and because the air is dry and won't conduct static charges well, and because your shoes and the rug are generally not conductors, you built up a healthy static charge. Then you provided a current path by reaching for the door knob. Electricity is "really fast" and the static charge could actually "feel" the metal of the door knob nearby as you reached for it. And because the voltage was so high, it ionized the air across the small gap between you fingers and the knob and current followed that ionized path. It was a case of a mini-bolt of lightning. Really! Not kidding! All kinds of friction brings with it the possibility of separating charges. And the charges separate all the time. We just don't generally notice it because the charges are constantly trying to neutralize themselves and no significant charge buildup occurs - unless its a warm dry day and we zap ourselves or there is a thunderstorm. Separating charges isn't that tough. Unroll some plastic kitchen wrap. Every time we do that, we participate in an experiment with static electricity. You've done it yourself. Separating charges is not difficult, but conditions have to support "keeping the charges apart" for a charge to accumulate. As the kitchen wrap is a poor conductor, separated charges "stay separated" and we have to battle the stuff to keep it from balling up on itself. That's not too difficult to grasp, either, is it? Nope. So we're back where we started. Your silk cloth is not positively charged. But it can be used to separate charges by rubbing it on that balloon we mentioned. And because the silk cloth and the balloon are not willing to conduct electricity, the charges stay separated and can be built up to some extent. You'll find some links below to relevant Wikipedia posts.
How do you identify if a substance is metal matalloid or non metal?
In simple terms just by looking at them, and doing an electrical conductivity test you can tell the following. the metals are shiny and conduct electricity. The non-metals which are gases or liquids are easy to distinguish. The solid non metals such as sulfur are not shiny and do not conduct electricity. (graphite conducts electricity but is soft and not that shiny). The metalloids look a bit like metals but are very poor conductors of electricity.
What is static electricity in the easy form?
Easy static electricity
Why is static electricity called static?
Static (meaning it does not move) electricity is an electric charge which is stored. One way to generate static electricity is to rub two things together, and one of the materials picks up negatively charged electrons- making the item that has picked up electrons negative, and the other one positive. This charge does not move because of the material is resistant to flow, so there is no easy path for current flow. Capacitors store a static charge - an excess of electrons on on of the plates relative to the other plate. A capacitor can be 'charged up' via a battery or other voltage source.
it is dangerous to stick a metal knife into an electric outlet because?
A metal is a conductor and the electricity will easy flow through it
How does current electricity differ from static electricity?
Static electricity is the BUILT UP STORE of electron charges [e-] between a pair of objects, while current electricity is the FLOW of electrons between these objects. Static electricity is a transfer of charge from one static body to another, resulting in an imbalance in positive and negative charges, while electric current is the flow of electrons, from one static body to another.
Static electricity for kids-what is it static electricity and how is it created?
How does static electricity work?What is static electricity?1. Static electricity is a form of electricity that does not flow: it is electricity at rest. Objects carry positive electric charges when some of their atoms have fewer electrons than they should, and they carry negative electric charges when some of the atoms have more electrons than they should. An easy way to produce static electricity is to rub two objects (made of certain materials) together: this transfers electrons from one item to another, giving each a positive or negative charge. Positively and negatively charged objects are attracted to each other like magnets-because each wants to shed or acquire electrons. When static electricity becomes powerful enough, so many electrons jump from one thing to another that they cause a visible electric spark, which you will feel as a little "shock" if one of the things the electrons jump to you! (Loose electrons can attach to atoms in the surface of your skin.) Lightning, in fact, is really just a giant spark that results when static electricity builds up in a cloud during a thunderstorm.How does my hair stick up?2. As you remove your hat, electrons are transferred from hat to hair, creating that interesting hairdo! Remember, objects with the same charge repel each other. Because they have the same charge, your hair will stand on end. Your hairs are simply trying to get as far away from each other as possible!How does a balloon stick to the wall?3. When you rub a balloon against your clothes and it sticks to the wall, you are adding an extra of electrons (negative charges) to the surface of the balloon. The wall is now more positively charged than the balloon. As the two come in contact, the balloon will stick because of the rule that opposites attract (positive to negative).What is the difference between static and current electricity?4. According to traditional terminology, current electricity runs freely while electrical charges from static electricity generally do not move too well on their own. Current electricity or "charge flow," forces charged particles to flow through each other. In static electricity, also called "net charge," protons and electrons repel or attract each other. They cannot flow through the other, as is the case with electrical current.
Why are you less likely to get an electric shock after walking on carpet in humid weather than in dry weather?
in humid weather there is presence of water particles and water does conducts electricity,therefore easy to get an electric shock,unlike in dry weather where there is no conduction of electricity
Why does metal complete a circuit when you plug it into an outlet?
Metal is a good conductor of electricity hence it gives an easy path and completes the circuit.

What types of bonds do you think the good conductors of electricity have?
Good conductors of electricity typically have metallic bonds. Metallic bonds are formed by the sharing of electrons between metal atoms, allowing for the easy movement of electrons, which is key for conducting electricity. This shared "sea of electrons" allows the free flow of electric charge through the material.
Why does electricity always seek the ground?
Electricity always seeks the ground because it follows the path of least resistance. The ground provides a direct and easy route for the flow of electricity to balance out differences in charge.
What are the ways of producing static electricity?
There currently isn't a device in the commercial world that does this, because its not very practical and its not easy. Though static electric can be hundreds of volts, the amount of energy is very small when compared to normal electric currents. There has been recent developments in clothing which charge a battery. I believe this works by collecting static generated made within the specially made fibres. There is apparently a few different types of experimental devices that appear to collect electric from thin air. And I think some of the devices work by attracting large amounts of static electric. But large electric voltages have to be created in the first place to be able to collect the additional static electricity. Search for 'Spatial Energy Coherence' to find theses types of experiments. Some videos on youtube can be found also.
