Electric ovens, refrigerators, air conditioners, and electric space heaters are examples of electrical appliances. Computers, smartphones, mp3 players, radios, and cameras are examples of electronic appliances. Many electronic appliances can run on battery power.
What type of device is a refrigerator?
A refrigerator is an open system that dispels heat from a closed space to a warmer area, usually a kitchen or another room. By dispelling the heat from this area, it decreases in temperature, allowing food and other items to remain at a cool temperature.
Is refrigerator a device?
A refrigerator is a device which works on the principle that evaporation of a liquid gives a cooling effect.
What is an example of an electronic device?
Electronic devicessuch as computers, mobile phones, remotes, and camerasuse electric current to encode, analyze, or transmit information. A computer contains millions of tiny electronic components. Parts of a computer that transmit, process, or store information include the CPU, hard drive, ROM, and RAM.
Is your appliance electric or electronic?
You use electrical when you are talking in a more general way about machines, devices, or systems that use or produce electricity. Electrical is typically used in front of nouns such as equipment, appliance, and component.
Is refrigerator electronic or electric?
A refrigerator is an electronic device. Since it contains a compressor, can I say it is a mechanical device? – Quora. normal refrigerators use mechanical process to transfer heat from one region to other, compressing gas release heat and expanding or liquid to gas absorb heat energy.
What are refrigerators uses?
The fundamental reason for having a refrigerator is to keep food cold. Cold temperatures help food stay fresh longer. The basic idea behind refrigeration is to slow down the activity of bacte- ria (which all food contains) so that it takes longer for the bacteria to spoil the food.
Is a refrigerator conduction convection or radiation?
A refrigerator has many features which lower conduction, radiation and convection energy transfer to reduce the consumption of electrical energy. Refrigerators usually have a light coloured outer surface to reflect radiation, and so reduce heat entering the refrigeration compartment.
What are the 10 electronic devices?

What are considered electronics?
Electronics is defined as devices run by electric power or the field of studying such items. An example of electronics are radios, computers, and televisions. Electronic equipment, systems, etc.
What are five electronic devices?
This includes devices such as the following:
- desktop computers.
- laptop computers.
- mobile phones.
- tablet computers.
- e-readers.
- storage devices, such as flash drives.
- input devices, such as keyboards, mice, and scanners.
- output devices such as printers and speakers.
Is microwave electric or electronic?
A microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating.
Is a TV an electrical device?
TVs are normally classified as electronic devices rather than home appliances. Home appliances are more specific to systems like your dishwasher, refrigerator, or stove.
What are considered appliances?
An appliance is defined as a piece of equipment or machinery that is used to perform one or more household tasks, which describes a number of items in the home, including your dishwasher, washing machine, refrigerator, and stove.
What are refrigerators?
A refrigerator (colloquially fridge) is a commercial and home appliance consisting of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from its inside to its external environment so that its inside is cooled to a temperature below the room temperature.
What is refrigeration in food processing?
Refrigeration and freezing are techniques used for preserving food in low temperatures. These procedures slow down or stop most bacteria from dividing and thereby multiplying, but do not kill them.
What is refrigerator explain?
A refrigerator is a machine used for keeping things cold. It is sometimes called a fridge or an icebox.People put food and drinks in it, to keep those items cold or good (unspoiled) for a longer time. A refrigerator has a heat pump which takes heat away from the air inside the fridge.
Is a fridge a thermal conductor?
Traditionally, fridges and freezers have been insulated with polyurethane foam (thermal conductivity >0.020 W/m.K).A refrigerator with 56% of its external surface area covered with VIPs is reported to reduce the energy consumption by 21% compared to that consumed when using polyurethane foam.
What are the laws of refrigeration?
Refrigeration laws
- Heat causes refrigeration in vapor absorption refrigeration.
- On decrease of pressure, the boiling temperature decreases.
- Heat naturally flows higher temperature to low temperature.
- Clausius statement of second Law of Thermodynamics.
How does a refrigerator transfer thermal energy?
The key to how a refrigerator or other cooling system works is the refrigerant.As a liquid, the refrigerant absorbs thermal energy from the cool air inside the refrigerator and changes to a gas. As a gas, it transfers thermal energy to the warm air outside the refrigerator and changes back to a liquid.
What is non electronic device?
(?n?n?i?l?k?tr?n?k, ?n?n?l?k?tr?n?k) adjective. 1. not related to electronics.
