An incandescent lamp is an artificial light source produced by passing an electric current through a filament which then heats up and produces light. The glass that covers the hot filament prevents air from coming in contact with it so that the filament will not be directly damaged due to oxidation.The hallmark of an incandescent lamp is the shape of a glass ball in which there is a filamentThe development of the incandescent lamp began at the beginning of the XIX century. The history of the incandescent lamp can be said to have started with the invention of the voltaic pile by Alessandro Volta. In 1802, Sir Humphry Davy demonstrated that an electric current could heat a thin strand of metal until it glowed white.Function
As lighting for indoor activities such as study lamps or work lamps because the light intensity is not too bright so it is safe for the eyes. Can be used as a decoration that will provide an accent according to the theme of the room with variations from various forms of incandescent lamps.Incandescent lamps are marketed in various forms. and is available for a working voltage (voltage) that varies from 1.25 volts to 300 volts. in some countries the circulation of incandescent lamps began to be limited.a light bulb made of glass, a filament made of tungsten, a lamp base consisting of a filament, a light bulb, a gas filler and a cap
The size of the incandescent lamp is quite diverse, ranging from small to large
each size has a different voltage for example 40 wat, 60 wat and 90 wat
Its shape also varies from round, oval and oval

RADIO
Radio is one type of one-way mass media whose role is to convey messages (news, information and entertainment) to the public with a wide reach.Radio is a technology used to transmit signals by modulation and electromagnetic radiation
the benefits of radio are not only as a tool to get information, it can be used to listen to songs, vent media, and send messages.
The radio has a length × width × height, which is 200 × 117 × 65 mm and weighs 472 grams.
radio has a beam shape and some are shaped like a small tube
The parts of the radio and their functions:

- Tuning or tuning circle consists of several components that have different functions, such as capturing electromagnetic waves, as a current and radio frequency filter, selecting frequency waves and so on.

- Oscillators and mixers consist of several components that have different functions. These functions are connecting and disconnecting and stabilizing voltage, modulating signals and holding electric current.

- The intermediate frequency amplifier (MF/ IF) functions to collect unbalanced internal electric charges in order to store energy in an electric field.

- The detector consists of 2 components, each of which functions as providing direct electric current and as a variable resistor or rheostat in dividing the voltage.

The sound amplifier (AF) has a function to amplify sound vibrations. The final amplifier functions to increase and decrease the
voltage

LAPTOP
Laptop, sometimes called a notebook, is a battery or AC powered portable personal computer (PC) smaller than a briefcase.

A Refrigerator

Refrigerator is an electrical household appliance that uses refrigeration to help with food preservation. The invention of the first artificial model of refrigeration, which became known as the refrigerator, was invented by William Cullen, a Scottish doctor who observed that refrigeration had a cooling effect in the 1720s. From this, he learned that food would last longer if it was replaced, because bacteria cannot thrive at low temperatures.  Refrigerators are very popular household gadgets. Now, almost all households have refrigerators. A regular refrigerator is placed in the kitchen because it is generally used for food storage.
Refrigerators have become one of the needs that must be owned by every modern society. Refrigerator can serve to keep the food to stay durable and not rot. Besides that the refrigerator can freeze water into ice crystals for drinks. In general, 2-door refrigerators are 187 cm long and 86.5 cm wide and are rectangular in shape. In the refrigeration cycle, there are five basic components, fluid refrigerant, a compressor, which controls the flow of refrigerant, the condenser coils (on the outside of the fridge), the evaporator coils (on the inside of the fridge), and, something called an expansion device. In general, a refrigerator can be seen as a heat pump. It takes heat away from the air inside the fridge. The heat gets added to the air from outside. For this, it usually uses electricity. Parts of the refrigerator, food management,filled fridge,calendars & organization,the flexzone drawer.
If you do not have a refrigerator, then of course we will be difficult to keep food ingredients to stay durable within a few days. For this reason, the refrigerator is important for every family all over the world.

give detail explanation:
Alternating current ( AC ) is an electric current that reverses direction periodically and changes its magnitude continuously with time in contrast to direct current ( DC ) which only flows in one direction . Alternating current is a form of sending electrical power to businesses and homes, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances , televisions, fans and electric lights into an electrical outlet . A common DC power source is the battery cell in a flashlight. The abbreviations AC and DC are often used to mean only alternating and direct, respectively, as when they change current or voltage.
