When using electricity is 220 volts calculated to be cheaper to use than 110 votes?

Question

When buying something like an air conditioner, I wonder which if any is cheaper to operate over the other.

Answer 1

Watts = Volts x Amps
There is more loss on lower voltage lines due to higher amps(more resistance). So you will need thicker cable to get the same amount of watts. The loss is generally on the amps side and not the voltage.

Watts = 220 x 10(10% loss) :
W = 220 x (10x0.9)
W = 220 x 9
W = 1980 (on a 220Volt circuit)

Take the same AMPS x 2 (because of 220 = 110 x 2) with 15% loss on 110V
Watts = 110 x 20(15% loss)
W = 110 x (20x.85)
W= 110 x 17
W = 1870 (on a 110Volt circuit)

In this case yo lose 110Watts due to the 5% more loss on the lower voltage circuit.
One can not really say how much more loss there is on a 110Volt because every setup is different.
This is also why carrier lines is running at more than 30 000 Volts

Answer 2

Window air conditioners are usually 110 volts and central air is usually 220 volts (which provides more power). Either way the power company meter will charge for watt-hours used regardless of voltage. That said, it is convenient to use the wall electrical outlets for a window unit and special wiring (and breaker) for central air. It is not recommended to use a given room circuit for more than one major load (perhaps TV or AC but not both). To save money select the unit that does best the cooling job you desire (whole house or single room(s). Good luck.

Answer 3

Its not leakage, but I find 110 air conditioners are often too close to the maximum amperage the wires can handle, and much of the power used to run them gets eaten up in heating up the household wiring. I love my central air, and find it so much cheaper to run than window units that never cooled the house sufficiently

Answer 4

Why do no longer you purchase a a hundred and ten/220 transformer, purely verify the Amps on the dryer and get an appropriate one. in accordance to my wisdom, if on the dryer you have 5 Amps meaning 5X220=1100 Watts, this might desire to be balanced once you employ the a hundred and ten, so 1100/a hundred and ten=10 Amps As a end, if the dryer consumes 5 Amps on 220 it is going to eat 10 Amps on the a hundred and ten so which you will might desire to have a fifteen Amp circuit breaker on the line of the dryer, on the a hundred and ten part. i'm hoping this grew to become into sparkling.

Answer 5

Operational cost is probably less significant than installation cost.

It is often cheaper to WIRE with higher voltage because there is less current for the same power, that means the wires can be smaller.

Smaller wires, less copper, if you have a long run it can make a big difference in installation cost.

Answer 6

Power = Voltage (V) * Current (I)
Typically a system operating at 220V will draw half the current of a 110V system therefore using the same amount of power.

Answer 7

Generally, 220V line has less leakage (less Amps/current) than 110V. So, it's cheaper to transmit 220V to your home.
