Connect one end of a piece of wire to a battery terminal and the other end to the other terminal. The ends of the wire become oppositely charged and the electrons in the wire flow along it towards the positive terminal. This causes the chemicals in the battery to change and eventually they will all be changed and the battery will be flat. It will then be unable to keep the ends of the wire oppositely charged and the current will stop.
Or you could connect the wire to the terminals of a generator. The laws of magnetism will cause the generator - when it's turned - to charge the ends of the wire oppositely and a current will flow. But only while the generator is turning, because as soon as the electrons move down the wire they neutralise the charge, which must be replaced to keep the current flowing.

∙ 8y agoElectricity comes from many sources. Such as coal power plants, nuclear power plants and renewable energy sources such as wind, solar and hydroelectric dams.
There is a great EPA calculator to help you know which sources your electricity comes from and how clean they are:
If you live in Minneapolis, the four biggest sources of power are:
Nuclear: Mostly from the Monticello and Prairie Island Nuclear Reactors.
Coal: From the Big Lake Coal-fired Plant.
Wind: From the 11 Suburbs and farms to the West and South of the Metro.
Natural Gas: From the Calpine Natural Gas plant in Mankato.
These resources generally are consolidated into regional electric companies, which sell you the power they generate for a monthly bill, which you pay, so that the plant can buy more of its fuel source to make more power for you or maintain the machinery that generates the power, like the steam or wind-driven turbines.

Electricity is generated by moving electrons through a media. A magnetic flux is required to generate this electricity. A magnetic field hits a medium i.e. gas or conductor. The electrons of this media will move on a close circuit. This movement is called current. A lightning is one sample of flux tru gas media. All those mentioned above on the first answer uses this magnetic flux.

Does a voltage source have resistance?
Voltage source: is any source that voltage and amperage come from. Resistor: is any part of a circuit that consumes that energy!
How a bucking voltage acts?
bucking voltage is a voltage which is of opposite polarity to the voltage it acts .
What is voltage transformation ratio?
ratio of secondry voltage to primary voltage is called voltage transformation ratio
What is the voltage that supplies a motor starter called?
In the electrical trade it is called control voltage. This voltage can be any voltage. In North America the common control voltage is 120 volts.
How do we adjust the voltage of a shunt generator?
The voltage is adjusted with a potentiometer that adjusts the field voltage through the voltage regulator.
Where did the word voltage come from?
From Voltaire-a scientist.
How does voltage come from a candle?
It don't, there is no electricity in a wax candle.
Does a voltage source have resistance?
Voltage source: is any source that voltage and amperage come from. Resistor: is any part of a circuit that consumes that energy!
What is voltage required for desktop?
Desktop computers all come with a power supply that changes the mains voltage in your country's electricity supply to that needed inside the PC. Thus the Voltage used by your PC is the mains voltage in the country where the PC was sold.
How will come to know whether current is lagging the voltage and vice versa?
Use an Oscilloscope
Why do you get low voltage when you put on the brakes?
The brake lights come on. The alternator should maintain voltage (14.2) unless the alternator is failing or the battery is nearing end of life.
Why does the battery light come on when you accelerate?
The alternator may not be able to keep up to the voltage requirement of the vehicle check voltage output of alternator w/mechanical gauge
Why using electrolytic capacutor for dc voltage?
Electrolytic caps are polarized and come in larger voltage rating and larger cap size than other types of capacitors.
What is the voltage volts for the throttle position sensor and where does the voltage come from on a 94 potiac grand am?
the voltage "persay" comes from the ecu(computer) i would not use a test light to see if voltage is present thay can be intrusive and short the ecu u will need a dvom meter and service manual to test that circut
Even if the battery is dead shouldn't light come on when i hook up battery cables?
NO! where does the power (voltage and current) come from if the battery is flat/dead?
Will your battery light come on if your Voltage regulation is bad?
If it is undercharging the battery yes, but if it is overcharging the battery no in most instances. If it fails completely the light will come on.
What is the value of the breakdown voltage for zener diode?
It depends on the particular diode. They come in all different values.
