Does higher voltage take less electricity than lower voltage?

Answer 1

Yeah it is true

Answer 2

a higher voltage will use less current (amps). for example, a 60 Watt 120 Volt light bulb will use 1/2 of an Amp. (60 / 120 = 1/2). a 60 Watt light bulb using 12 Volts will draw 5 amps. ( 60 / 12 = 5) the wattage is the same but the current is different. you get charged by the power co. by KWh (kilo watt hours, or how many thousand watts per hour used). so it really doesnt matter. what the main reason for using the higher voltage is that the less current you draw, the smaller the wire has to be ( big wire costs more then little wire). thus the appliance can run more efficiently. If you live in the US, and you want to buy say a 10HP air compressor, you might want to buy the 220V version because the draw is less. the only problem is you would have to install a circuit with 2 hots.

so no it does not use more watts( doesnt cost more/less) but it does use more amps

Answer 3

The main advantage is smaller wire size for the Higher voltage

Answer 4

It is cheaper to use a higher rated voltage item than a lower voltage item as your meter registers amperage usage. Higher volts use less amps ( generally)

Answer 5

To deliver a given wattage, a higher voltage will require a lower current.
For a 1200W 120V heater the current will be 10A.
For a 1200W 240V heater the current will be 5A.
Power (Watts) = Volts x Current (Amps)
