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.
Voltage source: is any source that voltage and amperage come from. Resistor: is any part of a circuit that consumes that energy!
bucking voltage is a voltage which is of opposite polarity to the voltage it acts .
ratio of secondry voltage to primary voltage is called voltage transformation ratio
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.
The voltage is adjusted with a potentiometer that adjusts the field voltage through the voltage regulator.

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.
Voltage does not come from a candle. A candle produces light and heat through a chemical reaction when the candle wax is burned. Voltage is typically generated by batteries or power sources that convert energy from various sources into electrical potential.
Use an Oscilloscope
The alternator may not be able to keep up to the voltage requirement of the vehicle check voltage output of alternator w/mechanical gauge
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.
Electrolytic caps are polarized and come in larger voltage rating and larger cap size than other types of capacitors.
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
NO! where does the power (voltage and current) come from if the battery is flat/dead?
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.
analog Voltmeters come in both forms depending which one you buy.
