Hpw would i make a doorbell using an electric circuit?

Question

all i have is a battery and a wire

Answer 1

You wind the wire into a coil say 100 turns round a nail if its allowed. Next get some sort of bell and clanger which a nail would work as at a pinch. Fasten it up in a way that the clanger hangs between the bell and the coil.  Next you will atatch a wire to the nail, bell and coil and a switch all in series in a way that the clanger touches the metal bell making a circuit and energieses the coil.  The coil becomes an electro magnet and attracts the hanging clanger towards it. This breaks the circuit and the coil looses its magnetism. This releases the clanger which drops back striking the bell and making a noise. The circuit is completed again and the process is repeated to make a ringing noise

Answer 2

you'll need,

1. battery

2. buzzer

3. switch

connect all of them in series using wires. when you close the s/w, buzzer sounds. when s/w is open, buzzer is off.

use the kind of s/w used in practical doorbells.

Answer 3

This isn't quite enough.  For one thing, you need something that makes sound.  The simplest way is to add a switch (button) and a electric bell.  Just wire everything in series.  If the battery is the correct voltage for the bell, when the button is pressed, the bell will ring.

Answer 4

Get a switch, electronic shop.

Get a buzzer, piezo buzzer at electronic shop.

You connect the wire to the one side of the battery, black or - to the black - wire on the buzzer. You connect the wire to the red + terminal on the battery to the one connection on the switch. then connect wire to the other side of the switch and connect it to the red wire on the buzzer.

Plan B buy all the stuff at the electronic shop and ask them to show you, I do that sometimes, no doubts then.
