Battery Boxes & Switches
Plastic moulded holder with brilliant finishing to hold cell of 1.5 volt, big size. Individual units can be joined in a tandem to make a battery of required voltage. Sockets of 4mm are provided on the cell holder.
Dimensions: 74x38mm (L x W), Single holder
Single cell
Double cell
Four cell
Battery Holder
Cell Battery Holder with Fahnstock Clips
Cell Battery Holder with Leads
Each type holds all standard D cell batteries and comes with 6 red and black pre-stripped leads or Fahnestock clips for easy connection. Made of unbreakable plastic. Curved sides help prevent the battery from falling out when it is upside down.
BELL EXPERIMENT
Exp-1 To demonstrate that sound require a medium to transmit.
Exp-2 To demonstrate the atmospheric pressure.
Bell experiment : A sound wave is a longitudinal wave and it requires a material medium to transmit. Sound originates from bell. As the air is pumped out of the sealed bell jar, the sound from the bell jar fades. After sometime, no more sound is heard from the bell.
