120 Volt Vs 220 Volt

Posted on  by admin

You'll often hear voltages in your home referred to as 110V, 115V, or 120V. This can be confusing but the bottom line is they are referring to the exact same thing. 120V is the AC voltage on a single hot wire in your home with respect to neutral (or ground). Click to see full answer. Similarly, is 110v the same as 115v? The outlets are standard 110V.

The air conditioner unit is listed as 115V. Also Know, is 115 volts a regular plug?


In most homes, the standard household voltage is 120 volts. The power company supplies two, 120-volt cables, or legs, of electrical current to your home. Wires going to standard receptacles in your walls are 120 volts and are suitable for 110-volt or 115-volt air conditioners. Similarly one may ask, are 115 volt and 120 volt the same? So that would mean your voltage should be between 114 and 126 volts.

is now 120/240 volts. Most electric motors and many electrical appliances (especially those with motors) have a nameplate rating of 115 volts (meaning that they're designed to run optimally at 115 volts).

Does Wiring a Motor at 240V Save Electricity over Wiring it to Run at 120V?

What is the difference between 110 and 120 volts? 110 volts vs.The important difference is the amount of potential energy, or voltage, the socket is able to supply to the device plugged into it. Sometimes you may hear 110 volt plugs referred to as 120 volt. Do not be confused by this; think of them as one and the same.

"If I run my lights at 240 Volts instead of 120 Volts, will I use less electricity?" Here at Black Dog LED headquarters in Boulder, Colorado, we are asked this question quite often, and the simple answer is yes, but only by a little. All electrically powered devices consume watts, and wattage is what you are paying for.

Converting 120volt to 220 volt

Volts and amps are not an important factor related to electrical expenditures in an existing wired garden, although when building a new area or adding additional power to an existing area there is a possible savings in material costs and labor. To understand why there is no large electrical savings, a brief review of these electrical terms is helpful.

Below we discuss Volts, Watts, and Amps, including some advantages and disadvantages of running LED lights and other indoor garden equipment at different voltages. Voltage, wattage, and amperage; or volts (v), watts (w), and amps (a) are terms commonly used to describe and measure electricity. Voltage or Electric Potential is the amount of electrical energy available at a source such as a plug, breaker, or extension cord—essentially how hard electricity is "pushed" through a wire.

Thinking in terms of a water hose, voltage would represent the pressure of the water flowing through it. Amperage or Electrical Current is the amount of electricity transferred or moved through a wire or circuit.

In a water hose, it would be the volume of the water flowing through it. Wattage or Electrical Power is how much "work" the electricity does, such as energizing the diodes in a LED grow Light.

Continuing the water hose analogy, if the water exiting the hose hits a paddle wheel, the resulting rotation (work) of the wheel represents the wattage. Your power company bills you based on the watts you use, not the voltage or amperage. Below is a simple formula for determining voltage, amperage, and wattage:. Reviewing the formula, we see that watts are determined purely by voltage and electrical amperage, so for a device requiring a particular number of watts, as voltage increases, amperage decreases. While there are some allowances made outside the scope of this article, this tip holds true for most electrical devices designed to operate at variable voltages.
