Relay on The Car Horn

One way that we can do to make our car horn sound louder is by pairing a relay on the horn circuit, with the addition of a relay to the horn system, of course the electric current is made shorter without having to pass through the main switch.

With this circuit circuit shorter, the current from the car battery will not decrease and will go directly into the horn so that the horn sound becomes loud.

This is different if the horn circuit is not paired with a relay, the current that was originally large from the battery will go to the switch, in this case the horn button is on the steering wheel so the current becomes reduced. It is this reduced strength which causes the horn to sound less loud.
