Did you know that each type of electrical appliance converts electricity into different forms of energy to run? In this article, Tran Phu will bring the most comprehensive information about electrical appliances: how are they classified by the types of energy they transform, the technical data that everyone should know.
Classify household appliances
Electricity is converted into different forms of energy in electrical appliances. Based on this principle of electricity conversion, they are classified into the following 3 groups:
(1) Electrical - optical appliances which convert electricity into solar energy for lighting. For example, there are fluorescent lamps, incandescent lamps, etc.
(2) Electrical - thermoelectric appliances which convert electricity into heat energy for warming, heating, drying, and so on. For example, fireplaces, hair dryers, etc.
(3) Electrical - mechanical appliances which convert electricity into mechanical energy to actuate, milling, etc. For example, electric fans, blenders, etc.
Luminaries are a type of electrical - optical appliance

Important technical data of electrical appliances includes:
Rated electrical quantities:
(1) Rated voltage (U) - unit is volts (V)
This is the most important measure of electrical equipment. It determines the load capacity of the grid as well as the structure, equipment and cost of the equipment.
(2) Rated current (I) - unit is ampere (A)
The rated amperage is the intensity that will help the device work with the highest power. This is the tolerance limit of the current. If the current exceeds the rated value, it will cause damage to the appliance.
(3) Rated power (P) - unit is watt (W)
This is the measure representing the most capacity of the device that can be operated so as not to be disturbed or damaged.
The specific quantities for the utensils function such as pot capacity, jar, etc.
The meaning of technical data
Technical data help us choose electrical appliances that match our needs and use them with the right technical standards.
To avoid damage to electrical appliances during usage we should pay attention to these details:
Match electrical appliances to a mains voltage equaling to the rated voltage of the electrical appliance.
Do not use electrical appliances beyond their rated capacity
Use the accompanying equipment such as high-quality and reputable wires and switches.
Knowing the basic knowledge of electrical appliances and their technical data will help us a lot during usage so that you can optimize your usage and increase the performance of your device.
