This kit
explores the working of the electric bell and the electric
buzzer. Students and teachers can build the bell utilizing the
solenoid, its core the baseboard, the hammer and the bell gong
with other parts of the kit. The electric circuit for the working
bell is explained to facilitate easy wiring of the bell. A
schematic diagram links the mechanical operation of the bell with
the repeated interruption of current flow in the circuit in a
regular manner, explaining the "make" and "break" principle,
resulting in the hammer striking the gong.
This kit
operates on two size D batteries.
Batteries are
not provided with the kit.
