What is service mains in power transmission system?
A 'service mains' is not associated with an electricity 'transmission' system, but with a low-voltage 'distribution' system. The service mains is the name given to the cable that connects a building to the low-voltage mains supply.
What is used to provide low voltage enrgy?
Assuming 24 volts or lower is implied in the question, low voltage energy can be taken from a battery or from a low-voltage transformer fed from the house supply.
How do i switch a 3 phase motor from low to high voltage?
You can't. You must supply the motor with it's required voltage. If it's a dual voltage motor, follow the wiring schematic on the motor nameplate to switch from low to high voltage.
What is the advantage of using series parallel connection?
Series connection has only a single path through which the electron can travell,where as the parallal connection has many paths to travell the electrons.So in a serise connection if one of the component of the circuit is switched off,every other component of the circuit will be switched off. Fairy lights are usually series connected. The main voltage is divided across the number of lamps. So each individual lamp is low voltage.
Why dc components operate at low voltage compared to ac component?
Because equipment operating on DC is usually low-power electronic equipment, and it uses a power-supply to convert the house AC supply to DC at the right voltage. Most appliances needing high power are designed to run on AC because that is the normal supply to houses.

Advantage of low voltage over mains voltage?
Less likelihood of electrocotion.
Does a computer's power supply generate electricity?
In short, no. The power supply takes the alternating mains voltage and reduces it to the low voltages and direct current needed by the components of your PC.
What type of power does a power supply convert to?
A power supply is generally only converting the mains voltage down to a lower voltage suitable for low voltage equipment. It turns 120 v into 18v or 12v or 5v or any other voltage it is specified for. In most countries outside US, we have 220 volt AC in the mains. Power is however power. One could say that Voltage is the speed of which the power run. A power supply generally slows down the speed of electricity. Regards.
What is relay driver?
A relay is an electro-magnetic switch which is useful if you want to use a low voltage circuit to switch on and off a light bulb (or anything else) connected to the 220v mains supply.
What is Function of a power supply?
Power supplies are normally units that adapt the incoming current from a "mains" source and convert it to a lower (regulated) voltage that can be used by an appliance. They are commonly found in computers, charger units, low voltage lighting systems etc.
Can connect high voltage supply to low voltage device?
Yes, but it won't be pretty.
What is fuction of power supply?
The power supply makes the computer run, without any type of power supply it would be impossible to run a computer. The mains power supply for a laptop and the power supply unit of a desk top, both convert the high AC voltage from the mains power and convert it to low voltage DC, for the electronics of a computer to use.
What to do if the power supply is too low?
Obtain a power supply that has the correct output voltage that you need.
What are the best LED replacement bulbs?
It really depends on where you are going to use the bulbs!All the light bulbs do not operate the same voltage for starters, there would be nothing surprising about that, but unless you are aware of the differences between them you could be in a little shock. LED bulbs come in two primary voltages: mains voltage and low voltage.Mains Voltage BulbsThe mains electricity supply in the United Kingdom is 230 V Ac (Alternating Current). This is used to supply the majority of domestic and commercial lighting.LED (Light Emitting Diodes) operate at low voltage DC (Direct Current). As such, LED bulbs that are designed to run straight off the mains, like GU10, B22 or E27, require a driver to change the voltage from 230 AC.You will observe about GU10 LED bulbs (230 V) is that they are slightly longer than the low voltage MR16 bulbs(12 V). This is due to the fact that the driver unit is placed into the GU10 fitting.Low Voltage BulbsLow voltage bulbs, are simply lights that run at a lower voltage than provided by the mains electricity supply. They used to exist in the cars where connecting to the mains electricity supply was not viable and the lights would have to run off either a 12V or 24V engine battery instead.Low voltage lighting in houses is a recent innovation. It is created primarily for fittings in kitchens and bathrooms. Instead of being connected directly to the mains supply, an intervening transformer 'steps down' the mains voltage.When you exchange your old halogen bulbs for MR16 LED, there is no guarantee that they will work with your existing 12 V transformer. Contact your retailer to determine whether or not you need to upgrade your system.LED lights have come a long way in the last few years and so have the prices so keep looking. Any good LED lighting website will have info on which lights are best for the application you need them for so have a look around.

How do you solve low voltage supply?
Put a seprate transformer. It will solve this issue
