How electrical appliances are rated in watts?
These figures are usually displayed on a rating plate attached to the appliance, e.g. 230 volts, 3 amperes. The rating of the appliance is related the power it consumes. Power is measured in watts and is the product of volts and amperes. The example above would have a rating of 690 watts.
Does wattage matter for appliances?
The job of a power supply is to provide power to the connected device or appliance. So, it would make sense that the more power a device or appliance requires, the higher the wattage you’ll need from the power supply. Higher wattage = more power.
What rating indicates the amount of power consumption of an appliance per hour?
The unit on the electricity bill for electrical energy used at home is kilowatt-hour or kWh. 1 kilowatt-hour represents the amount of energy consumed in 1 hour by an electrical appliance at the rate of 1 kilowatt.
