Understanding The Rating of Your Appliance
The capacity of an electrical field to do work is measured in volts. The voltage used in normal household in North America differs from that used in Europe and other parts of the World. The normal household voltage in North America is normally called 110 volts although the actual voltage may differ. Electrical Appliances sold in North America would have a voltage rating of 110v. Certain larger appliances such as washing machines and dryers operate on 220v.
Voltage is the potential electrical flow, but the actual movement of electrical current is called amps. Amps are another electrical rating used on appliances. An appliance is said to "pull" a certain amount of amps. A larger amp rating on an appliance would indicate that it draws more electrical power into the unit when it operates. When an appliance is rated by it amp use, more amps would indicate a more powerful unit. A vacuum cleaner that pulls 12 amps would generate more suction power than one that is rated at 6 amps. Some vacuum cleaners with higher amp rating will advertise this fact on the face of the machine itself.
Another term used in the rating of electrical appliances is watts. Watts is a measurement of actual work performed by electricity. The watt is a familiar form of rating in a wide variety of electronic products. Audio speakers are normally rated in Watts. Wattage can be determined by the formula Amps x Volts = Watts. It can also be said concerning watts that the higher the watt number the more powerful the machine.
The various ratings of electrical appliances are used in different manners. Voltage rating is the most important as it determines the suitability of the appliance for use in certain conditions. Amp and Watt ratings are used to determine the relative power of an appliance as compared to other similar appliances. In most cases the voltage, amps, and watt ratings of an appliance are displayed on a label on the actual appliance. If this is not the case, the information can be found in the operator's manual.
The watt and amp ratings can be viewed in two ways. Appliances with high amp and watt ratings are more powerful and the higher ratings would normally indicate that the appliance performs the work it is designed to do more efficiently. However, with the rising cost of electricity, people are looking for appliances that do the job required with the least amount of amps.
