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

| January 7, 2021 | education

Electrical appliances can be connected in series or in parallel.
– With a serial connection, the current in the entire circuit will be the same, and the voltage on each of the devices will be different, and depend on the resistance of the device.
– With a parallel connection, the voltage applied to the devices will be the same and equal to the mains voltage, and the current in the devices will be different and will depend on the resistance of the device.

Household appliances are designed to operate from a 220V network and different appliances consume different currents.
If you connect such devices in series, then the same current will flow through them (which is wrong) and a different voltage will be applied to each device, less than 220V (this is also wrong). As a result, the devices will either not work at all, or they will work, but not at full capacity.

This means that such devices must be connected in parallel – the same voltage will be applied to each device – 220V, and the current will flow through each device different.



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.
