A low voltage electrical system consists of a transformer and an output of about 12 volts. It is frequently used by a home owner to run a wire along the ground to put lights along a walkway. If an animal bites the wire or someone cuts the wire and touches the loose ends, he will get a shock but it will not do major damage. Unlike regular house current, it will not kill.
AnswerAccording to BS 7671:2008, Requirements for Electrical Installations, more commonly known as the Wiring Regulations, nominal a.c. voltages are defined in the UK as follows:
In general it usually means circuits that operate at a voltage of less than 30. 12 volts is a common value for low voltage lighting, there are others too. A step-down transformer converts the utility power to a low value to feed the lamps.
The only energy difference would be in the current that is drawn by the coils in the low voltage relay and the transformer that produces the low voltage for the coils. Low voltage lighting is for aesthetics only. The system is more expensive to install due to the remote locations of the relays.

A lamp will produce its rated power at its rated voltage. These values are printed on the glass envelope or its bayonet/screw fitting.
Power is defined as 'the rate at which energy is consumed'. So a 50-W lamp rated at 12 V will consume EXACTLY the same amount of energy as a 50-W lamp rated at 120 V, or a 50-W lamp rated at 230 V.
'Solar', in this context, simply refers to electrical energy generated by photovoltaic cells. On the other hand, 'low-voltage lighting' generally refers to a lighting system (often outdoor) supplied (typically at around 12 V) from a transformer connected to the residential supply (120 V in North America; 230 V in Europe). Of course, solar energy could also be used to provide 'low-voltage lighting'.
the voltage less than the required voltage to work a device or circuit is ment to be low voltage. For example if a bulb needs 10v to work properly, if we give only 6v the bulb glows but it glows dim which means that proper voltage is not supplied. hope u got the answer............
According to the 17th edition regs in the uk. It is anything under 1000 volts
no
AnswerYou are charged for the energy consumed. So if your low-voltage lighting uses less energy than a comparable conventional voltage lighting then, yes, it will be cheaper. To determine whether this is the case, you need to compare the total power of the low-voltage lighting system with the total power of a conventional system. If it is lower, then it is drawing less energy over the same period of time and, therefore, cheaper.
The classifications of voltage are as follows;High voltage — any voltage exceeding 750 V.
Low voltage — any voltage exceeding 30 V but not exceeding 750 V.
Extra-low voltage — any voltage not exceeding 30 V.
no
Yes. I think that is a definition of current.
voltage: it is the potentail difference between two wires. or it is the amount of energy used to force the electrons.current: it is the flow of free electrons.by Balaji,NITCAnswerThere is no such expression as 'potential voltage'. 'Voltage' is simply another word for 'potential difference'.
No. Voltage is the potential difference in energy between two charges. (Volts is joules per coulomb.) Since it is potential, that means it is relative, and in order to be relative, there must be two terminals.
there is a difference in electrical potential energy.
Voltage Rise : The energy added to a circuit. Voltage drop: The energy removed from the circuit.

As far as I know, no practical method has yet been found to put energy from lightning to practical use - or, for that matter, the voltage difference between the clouds and the Earth.As far as I know, no practical method has yet been found to put energy from lightning to practical use - or, for that matter, the voltage difference between the clouds and the Earth.As far as I know, no practical method has yet been found to put energy from lightning to practical use - or, for that matter, the voltage difference between the clouds and the Earth.As far as I know, no practical method has yet been found to put energy from lightning to practical use - or, for that matter, the voltage difference between the clouds and the Earth.

Voltage.The correct term for the amount of energy per unit of charge is potential difference.Energy = Charge * VoltageSimple rearranging gives: Voltage = Energy / ChargeTherefore a volt can be defined as a "joule per coulomb".
The relationship between energy and charge is potential difference or voltage. Where a volt is defined as existing between two points in an electric field when one joule of energy is required to move a charge of one coulomb between the two points.

Half a volt, because the energy is the charge times the potential difference.Another AnswerYou should be asking what the 'potential difference' is between the two terminals, not the 'potential'. Note that 'voltage' is another term for potential difference.
Either potential difference (apply voltage) or energy input (drag the charged particle)
