The purpose of a doorbell transformer in a home electrical system is to reduce the voltage from the main electrical line to a lower voltage that is safe for the doorbell system to operate.
To supply the bell, because the latter has a rated voltage that's lower than the mains.
pupose
Electrical bell is used for domestic purposes in house, home or in vehicles
A electromagnetic bell works by a electrical circuit.
A door bell works when the electrical circuit is complete. It doesn't work when there is no complete circuit. If it is just buzzing then there must be some electrical circuit, even though no-one is pressing the button.Somewhere there is a faulty connection, one that is making a slight contact, but insufficient to make the bell ring properly. Or maybe the 'ding/dong' unit is faulty.There are several things that could be done:# Rewire the whole thing. # Check the bell push, perhaps it is corroded or otherwise faulty. # Get an entirely new bell system. # Check all the wires, especially all connections. # Get someone who knows about electrical bells/circuits to check it for you. # If you rent the property and the bell is not yours but belongs to the landlord, maybe you could/should tell the landlord.
Umm let me think. NO!
Bell System was created in 1921.
Bell System ended in 1984.
Alexander Graham Bell.
The Bell System was broken up in 1984

The key is the door bell specification. They typically run on a 24 VAC transformer. You can certainly hook it up and try it with 9 volts, but it probably won't work as intended. 24 Volt transformers are relatively cheap.
