Why do household appliances in the room need to be connected in parallel?

In the event that we connect household appliances in series, and not in parallel, if the device in front fails, voltage will not come to all subsequent ones, since the electrical circuit will not be closed.

Because of this, even working devices that are located behind a failed one, despite their operable state, will be impossible to turn on.

In addition, devices must be connected in parallel because they are designed for equal voltage, and when connected in series, a lower voltage value will come to each next device.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
