Why are lamps in homes connected in parallel?
Lights in homes are connected in parallel, true or false
Yes, lamps in homes are connected in parallel
It is noteworthy that electric lamps became widely used in homes after the end of the first quarter of the twentieth century, and at first they were only present in the United States of America, but by the middle of the twentieth century, electric lamps had spread around the world and became present in most homes, except in some countries. Very poor or primitive, like some countries on the African continent.
Why are lamps in homes connected in parallel?
So that the residents of the house can turn on or off any lamp in the house without having to close or open another lamp inside the house
In general, the electricity that exists inside homes depends on the idea of connection in parallel. This is because connection in parallel allows a lamp to be turned off without causing the rest of the other lights in the house to be closed, for example. Connection in parallel also allows any electrical device in the house to be turned on or off. Without affecting lamps or other electrical appliances.
Components of household electrical lamps
Electric household lights are made up of the following components:
- Tungsten filament.
- Lead wire.
- Copper wire.
- Stable gas.
- Heat resistant glass.
- The metal lamp base that connects the lamp to the electrical circuit.
Electrical circuits
An electrical circuit is the closed path through which electrical energy flows . Electrical circuits are divided into two types:
- Electrical series circuit.
- Electrical parallel circuit.
The difference between series connection and parallel connection
| Straight delivery | Connecting in parallel |
| In a series connection, it is not possible to open or close any lamp or electrical device connected to the electrical circuit without affecting other lamps or devices connected to the same circuit. | In parallel connection, each lamp or electrical device connected to the circuit is independent, which means that any electrical device or lamp connected to the circuit can be turned on or off without affecting other electrical devices or lamps connected to the same circuit. |
| The electrical circuit in series does not work when there is a defect in any part of it. | The parallel electrical circuit works even when there is a defect in one of the secondary electrical circuits connected to it. |
| In a series electrical circuit, the current passing through each secondary circuit is the same as the current passing through the entire electrical circuit. | In an electrical circuit connected in parallel, a portion of the electrical current in the electrical circuit passes through each secondary circuit, knowing that the sum of the parts of the currents shows the current in the electrical circuit. |
The relationship of the electrical switch to the electrical circuit
An electrical switch is a part of an electrical circuit that closes it to encourage electrical current to flow through it or opens it to disconnect electrical current from it
It is noteworthy that the electrical switch may also control the transfer of electrical current from one electrical circuit to another, and the electrical switch exists only in an open or closed state, and it cannot be half open or half closed. If the electrical switch is turned on, the switch is connected to the circuit. Electrical, but if it is turned off, the electrically conductive metal is separated from the electrical circuit.
A mind map showing the difference between types of electrical circuits
Below we will display an image of a mind map that explains the difference between series and parallel connections:
What does it mean to break an electrical circuit?
Breaking an electrical circuit means cutting wires connected to each other to transmit current in a specific environment
An electrical circuit does not work unless every part of it is sound and connected to the other, and this does not contradict the fact that an electrical circuit connected in parallel can work with damage to some of the circuits emanating from it.
The secondary circuits in the parallel circuit are not usually closely connected to the original electrical circuit, and the entire electrical current does not flow in those secondary circuits. Rather, only a portion of the current flows in them, which means that the rest of the electrical current will remain in the remaining healthy secondary circuits. Naturally, when one of the secondary circuits in the primary circuit connected in parallel is damaged.
What happens in the electrical circuit when the electrical switch is closed?
A break occurs in the electrical circuit
When the electric switch is opened, metal legs extend and connect to the electrical circuit, causing electric current to flow through the light bulbs. When the electric switch is closed, those metal stems are withdrawn, causing a break in the electrical circuit and the electric current stops flowing in it.

Jezli website for purchasing electrical appliances
When we say Jeezly website, we are talking about one of the most famous Arab websites that was able, in a very short period of time, to achieve a very large demand for purchases from it by people from various parts and sectors of the Arab world.
On the Jeezly website, you will find a joint look and all the products that you may need in your home, starting with those for kitchens or bathrooms, but even those for gardens, you will find them on this wonderful site.

One of the most prominent features of the site is the proportionality of prices. On the Jeezly website, you do not have to worry about the imaginary prices of the products, as is the case with most sites that display their products on the Internet.
The price of delivering products is very reasonable and not expensive, and the site accepts delivery to various countries, without forgetting that it accepts free shipping on some products.
One of the advantages of the site is also the high quality of its products, as it is impossible to find a poor quality product. Rather, the Jezli website deals with major companies, Philips, for example, and other famous brands, so you must remove from your mind the idea of the poor quality of one of the products. Another advantage of the site is that it does not specialize in one type of product, but rather you will find various types of products on it, for example, electrical appliances, hand tools, mechanical devices, paints, packages for establishing apartments, and many other types.
Jeezly website also accepts what is known as the shopping cart, which makes it easy for you to filter the products you want to buy and put them in one package in order to be able to pay with the click of a single button.
Accepts multiple payment methods.
