Introduction to the Electric Bell Working Model
In this model, the metal box serves as the bell, while the DC motor, which is tied with a metal bolt, acts as the striker. The DC motor is connected to a 9V battery, which provides the necessary power to drive the motor. When the circuit is completed by pressing a switch, the motor begins to rotate, causing the attached metal bolt to repeatedly strike the metal box. This continuous striking action produces the characteristic ringing sound of a bell.
The working principle behind this model is based on the conversion of electrical energy from the 9V battery into rotational mechanical energy by the DC motor. As the motor rotates, the attached metal bolt repeatedly makes contact with the metal box, creating a sound similar to that of a traditional electric bell. The design effectively demonstrates how simple components can be combined to replicate the operation of an electric bell.
