What does the amp rating on an appliance mean?
The rating of an electrical appliance indicates the voltage at which the appliance is designed to work and the current consumption at that voltage. 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.
What is the purpose of amps in electricity?
An ampere is the unit used to measure electric current. Current is a count of the number of electrons flowing through a circuit. One amp is the amount of current produced by a force of one volt acting through the resistance of one ohm. (An ohm is a way of measuring resistance.
How many amps does appliances use?
In most homes, lighting and small appliance circuits are 15 or 20 amps, and major appliances are on 20, 50 or even 60 amp circuits. Second, the volts flowing through the wires. Volts are a measure of the pressure that causes current to flow through a circuit. Generally, household wiring is 120 or 240 volts.
Why are appliances rated in watts?
Watts is specified since that’s the work that’s being done by the appliance when it’s ON, and that’s what your power company is charging you for. Watts*hour is what you are paying for to the electricity supplier. It is a power, or energy per unit of time consumed by the appliance.
How do you find the power rating of an appliance?
Power ratings of most appliances are usually listed on the appliance itself or the manual. For a final calculation of your watt-hour usage, we recommend that you look at each appliance to be powered to find its rated power.
What is amperage in simple words?
Definition of amperage 1 : the strength of a current of electricity expressed in amperes.
What is difference between voltage and ampere?
Voltage and amperage are two measures of electrical current or flow of electrons. Voltage is a measure of the pressure that allows electrons to flow, while amperage is a measure of the volume of electrons.
What is the power rating of a refrigerator?
Domestic fridge power consumption is typically between 100 and 250 watts. Over a full day, a fridge is likely to use between 1 to 2 kilowatt-hours (kWh).
How do you determine the power rating of an appliance?
It can be found in the user manual for the piece of equipment, printed on the transformer for the appliance, or stamped on the information sticker that is attached to the appliance. Multiply the value for the current by the value for the voltage to determine the power rating.
What is the power rating of home appliances?
