Do a 60 HZ appliance use more electricity?

Answer 1

The amount of energy used is really unrelated to voltage. The energy usage of a piece of equipment is related to the work done, and/or heat generated by that piece of equipment. Electrical power is equal to the voltage times the current (amperage). At 240 volts, the same amount of energy is produced using 1/2 of the current (amperage) draw than is required at 110 V. For instance, a 1200 watt appliance will require 10 amps of current at 120 V (120V x 10A = 1200W). The same appliance will require 5 amps of current to do the same job at 240 V (240V x 5A = 1200W). The energy usage (1200W x time) is the same in both cases.

Answer 2

The energy used by an electrical appliance is not only determined by its voltage but also by its electrical resistance.

It is very easy to ask this question but to give a useful answer to it, keeping it as simple as possible by not using many technical terms - yet still giving an adequate explanation - is much more complicated to do.

But here goes:

Electrical appliances which require 110-120 Volts may or may not use more energy than appliances which require 220-240 Volts. It is impossible to say without knowing more about the kinds of appliances being asked about and what energy or power they take.

Appliances which need to use a high amount of energy - such as water heaters, clothes driers and kitchen ranges or ovens - are often designed to use 240 Volts instead of 120 Volts because using 240 Volts means that the Current taken would be only half what it would be at 120 Volts to deliver the same amount of Energy or Power.

Being able to use a smaller current is important because it means that thinner wiring and smaller circuit breakers can be used to supply the appliance than would be necessary at 120 Volts.

Ohm's Law can be used to figure the current taken at any voltage if you know the resistance of the appliance:

I = V / R.

In words, Ohm's Law says:

Current "I" (measured in Amps) is equal to = Voltage "V" divided by Resistance "R" (measured in Ohms).

The Energy or Power taken by an appliance, measured in Watts, is given by the Power formula where Power is "P":

P = V x I

In words, the Power formula is:

Power (in Watts) is equal to Voltage "V" multiplied by Current "I" (measured in Amps).

Answer 3

The amount of electricity that an appliance uses is governed by the wattage that the appliance is rated at. This is indirectly governed by the amount of amperage that the appliance draws which is indirectly governed by the resistance in ohms that the appliance has. As to the frequency of the appliance, this has no direct bearing on the electrical consumption. A formula to keep in mind is Watts = Amps x Volts.

Answer 4

A 60 Hz appliance will not use more electricity compared to a similar appliance operating at a different frequency. The power consumption of an appliance is primarily determined by its power rating (in watts) and how long it's used for, regardless of the frequency at which it operates.

Answer 5

The frequency is unrealted to the energy. In electricity, energy = power x time, and power = voltage x current.
