Yes, a nail is a conductor of electricity because it is usually made of metal, which allows electrons to flow easily through it. Conductors like nails are used in electrical circuits to carry electric current.
What do you call the material that resist the flow of electric current?
The material that resists the flow of electric current is called an insulator. Insulators have high resistance to the flow of electricity and are used to prevent electricity from flowing where it is not desired.
What process uses electricity to seprate organic compounds?
The process that uses electricity to separate organic compounds is called electrophoresis. Electrophoresis involves applying an electric field to a solution containing the compounds, causing them to migrate at different speeds based on their charge and size, allowing for their separation.
What is the parts of fluorescent lamp and there functions?
A fluorescent lamp consists of a glass tube filled with mercury vapor and coated with phosphor. The tube is connected to electrodes at each end. When electricity is applied, the electrodes produce an arc, which excites the mercury vapor to produce ultraviolet light. The phosphor coating then converts the ultraviolet light into visible light.
What determines how severe an electric shock will be?
The severity of an electric shock is determined by the amount of current that passes through the body, the path the current takes, and the duration of the shock. Factors such as voltage, resistance of the body, and individual health can also influence how severe the shock will be.
What is one example of chemical energy to produce electrical energy?
One example is a battery, which converts chemical energy into electrical energy through a chemical reaction that causes the flow of electrons. This flow of electrons generates an electric current that can be used to power electronic devices.
What type of electrical outlet is used in Norway?
Norway uses:
Single phase 230 volts 50 Hz alternating current for small appliances in domestic dwellings (houses and apartments) and non-industrial non-domestic buildings (offices, shops, schools, etc.), for which the socket outlets and plug types are:
Type C: Standard European "Europlug" Outlet (two holes)
and
Type F: Standard European Earthed Outlet (two holes plus ground contacts)
For pictures of these outlets and the associated plugs see the Related link shown below.
What is the potential difference in electricity?
Potential difference, also known as voltage, is the force that drives the flow of electric current in a circuit. It is measured in volts and represents the energy per unit charge available to a charge to move in an electric field. A higher potential difference leads to a greater flow of current in a circuit.
How far should exterior electrical wires be from windows?
Far enough away that no one can accidentally reach them from the window. Electrical transmission wires should never be touched, but they need to be brought in to a fuse or breaker box, usually in the basement for single dwellings or some closet for apartments.

How do you install 120v outdoor lighting?
The same way as indoor lighting, but your fixtures must be rated for use in wet locations. This type of question usually means you aren't ready to do this yourself. Study some electrical material and the National Electrical Code and work this answer out for yourself, or call a professional electrician. If I were to give you an answer, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use an electrician's test meter having metal-tipped probes (not a simple proximity voltage indicator) to insure the circuit is, in fact, de-energized.
How do you convert 5 volts to 12 volts?
The 12 v side ampere rating is unnecessary information (You need 5 watts output power, so if the input is 12 volts, you need around 1/2A input current). Use a DC to DC converter. I found an IC made for this purpose at Radio Shack several years ago - I assume they are still available if you are a hobbyist. Otherwise you can buy premade ones (search for 12v to 5v converter).
How do you get a 110V outlet in a car?
You will need to purchase a power inverter. An inverter changes direct current, like what is in your car, to alternating current, like in a home. You will need to know the wattage of the item you are powering in order to buy the correct sized invertor.
Why must a circuit be closed in order for a current to flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
What color is ground wire in a home?
In a house, the ground wires are green, and in some cases, bare. The other wires in a typical house are black, red, and white. The red and the black wires are both considered "hot" wires, whereas the white wire is the neutral wire. The voltage between the red and black wires is 240 volts in the US, while the voltage between either of those and the white wire is 120 volts. The white wire and the green wire actually are connected together in the panel box. However, you are only allowed to connect the ground conductor and the white together just once in the panel box at the neutral block.
Can a black wire go with a black wire?
If you're asking this question you shouldn't be installing an electrical service of any kind.
This type of question usually means you aren't ready to do this work yet. Study some electrical textbooks and the National Electrical Code and work the answer out for yourself, or call a professional electrician.

Is voltage electrical pressure?
Yes.
If you compare the effect water pressure has on flow rates and from an open tap, more pressure allows more water to flow out of and away from the source.
In electrical circuitry, an increase in voltage - say from a battery - will in most cases
enable a larger current to flow around the circuit that the battery is connected to.
Voltage can be seen as the pressure force pushing another quantity around the loop and that quantity is electrical current .
Electrical pressure and the quantity of electricity transmitted can be considered analogous to water flowing in pipes.
Electrical pressure is called voltage: the longer the distances, the higher is the pressure (voltage) required to pump the current.
That is why, for long distance transmission, high pressure (voltage here) is required, failing which, the power will not reach the destined end. It will dissipate on the way.
<><><>
We can think of electrical current as the quantity of electricity which will be drawn from the pipeline (= cables for electricity) at the pressure (= voltage) required.
You can't "convert" a 120V receptacle into a 240V receptacle.
A proper new 240V branch circuit complete with correctly sized circuit breakers, wiring and socket outlet is required.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Multiplying 400 volts by 45 amps would give you a power output of 18000 watts, which is equivalent to 18 kilowatts (kW).
How do you check for a 240V electricity supply?
You should check for voltage with a meter or a test light. You should see 220V between both hots, 110V between either hot and neutral, 110V between either hot and ground, and 0V between neutral and ground.
A short circuit, or "short", occurs when uncontrolled electricity flows from the hot line to the neutral line or from the hot line to the ground.
<><><>
An unbroken short circuit is one of the causes of house fires if an electrical cable catches on fire because its circuit breaker has failed to trip.
Some reasons for this happening include:
- a breaker wrongly specified with an amperage that is too high for the circuit it is protecting;
- a faulty breaker;
- someone illegally replaced a breaker or a fuse with a length of heavy gauge wire.
<><><>
Your question is asking specifically what happens when a hot conductor makes contact with a ground or neutral conductor. To be frank, what happens is really no different from what happens when electricity flows through a device or appliance - an electrical circuit is created and electrical current flows around it.
The only bits of information you really need to know are that A) current is created by the flow of charged particles (typically electrons) through a conductor and measured in amps, B) the potential for this flow is a separation of opposite charges, typically called electrical potential and measured in Volts (V), C) almost all conductors and circuit elements have resistance, measured in Ohms, which opposes the flow of charge. A light bulb has much more resistance than a wire.
Finally, putting it all together, the relationship between current, potential, and resistance in a circuit is I = V/R. In other words, current equals voltage divided by resistance.
So let's take the example of a light bulb connected by wires to a power source. The wires have negligible resistance compared to the bulb. A typical household incandescent light bulb has a resistance of around 200 Ohms. The voltage supplied to most US household outlets is about 120 Volts. So 120 Volts divided by 200 Ohms gives us the current, which is less than 1 Amp.
Now, let's take the light bulb out of the mix and simply cross the two wires. The only resistance we can take into account is the very small resistance of the wires. At the most, this is only a few Ohms. If the wires are only a few feet long, the total resistance may be less than 1 Ohm. 120 Volts divided by .5 Ohm equals 240 Amps, which is a lot of charge flow.
This results in a few things. First, you see a big spark when you connect the wires. The wire heats up due to power being dissipated, which can also be calculated by squaring the current and multiplying by the resistance. For the light bulb, a current of .5 Amp and a resistance of 200 Ohms would give 50 Watts of power dissipation, which sounds like a reasonable light bulb. When the wires are simply crossed, squaring 120 Amps and multiplying by .5 Ohm gives 7200 Watts of power, which can toast a 16-gauge copper wire pretty quickly. Hopefully your circuit is protected by a 15- or 20-Amp fuse or circuit breaker, which will trip when current in the circuit rises above the breaker current rating.
How do you replace an electric stove with gas?
I would say it is impossible as they work completely differently.
For one thing there are no burner holes for gas on an electric stove! The control dials will have to be changed too. I just think it would not look very good sitting in a kitchen anywhere after it has been converted from one to the other. For all the time and effort I do not think it is worth it, it would be better to go buy a used one, and one other thing you might keep the hair on your head and face when you go to test fire the converted stove.

What is the result as static electricity charges move off an object?
As static electricity charges move off an object through a discharge, the object then becomes the same potential as the surrounding objects in the area.
What is the name for what happens when light is split up into the different colours of the spectrum?
Refraction is the name for what happens when light is split up into the different colors of the spectrum.
How many watts to run double fluro light?
It depends on the type of double fluorescent fixture and the tubes you use in it.
If you use regular T-12 tubes, you would use 80 watts plus whatever losses you get from the ballast (up to 20 watts).
If you use energy saver T-12 tubes, you would use 68 watts plus the losses from the ballast.
If you use a T-8 fixture, you would use 64 watts plus whatever losses from the electronic ballast which are next to nothing in comparison to a magnetic T-12 ballast.
