    220 V vs 110 V
    What is the difference between 220 V & 110 V and which one is stronger and why ?

    This site has some good information -- 110 volts vs 220 volts

    110 volts vs 220 volts - Tool Shed Forum - GardenWeb

    The difference is there is twice as much power -- what that means is

    A 110 volt motor draws 5 amps -- 220 volt motor draws 2.5 amps

    A 110v motor works harder -- A 220volt motor will run cooler and last longer

    To do the same amount of work - 220 volt motor better all around

    Power = Voltage x Current.

    So obviously 220 V is stronger than 110 V

    When you are discussing only on the stronger part of the supply ,Then 220 V is higher than 110 v .In 220 V system the current drawn will be very less when compared to 110 v.
    The lower voltage is safe always to use in control system rather in power system .If you have noticed in any elctrical system the control circuit will be of lower voltage like 12v,24v,48v,110v... These low voltages help in controlling the electric circuit & at the same time in case of any short circuit the fuse blow with less damage as the fuse will be lower based on the rating.

    Does that mean that running the same appliance with 220 vs 110 the 220 will consume less power meaning a small power bill?

    No. If you have an appliance that can run in either 110 or 220 (such as the power adapter on your laptop computer), it draws 1/2 as much current when plugged into a 220v source than it does when plugged into a 110v source. Remember that Power = Voltage x Current, so at double the voltage and half the current the power usage is the same. Your bill from the electric utility would be the same as well.

    Ahhh, OK thanks. Over the years I would hear folks talking about using 220 instead of 110 to save money? Guess they didn't have a clue. I like your avatar, used to watch Speed Racer every Saturday Morning.
    Thanks again
