Electric Bell Information:
An electric bell is a mechanical bell that functions by means of an electromagnet.
In DC electric bells, when power is applied, current flows through the coil. The coil becomes an electromagnet, attracting the metal strip. This moves the clanger to hit the bell, but also breaks the circuit. The coil is no longer a magnet, so the clanger moves back. The circuit is thus restored. The process repeats continuously until the power is removed.
AC electric bells do not have interrupting contacts and their coils are powered directly by the source. Their hammers vibrate at same frequency as the frequency of voltage they are powered by. Lack of contacts makes them more reliable than DC bells.
Some electric bells have two cups which generate different tones. When the hammer goes one direction, it hits one cup, when moves back, it hits another cup. The sound of such two-tone electric bell is more pleasant. |
