Demonstraton Electric Bell

Description

Enables students to investigate nature and properties of electricity by using simple circuits which are easily constructed on a base board. The connector system uses P.C.B. strips with cut-out sections whose ends can easily be inserted in spring terminals, ensuring low contact resistance and ease of connection. The kit consists of : 1. Baseboard, plastic, with spring terminals and three battery holders. (1) 2. Batteries. (3) 3. Lamps 1.25 V MES. (10) 4. Lamp holders mounted on PCB connectors. (6) 5. Plain connector PCBs. (10) 6.

Description

To demonstrate the characteristics of simple and primary cells. Consists of a plastic jar with a screw-on plastic rim containing two adjustable brass electrode holders, eight electrodes of different metals and a porous ceramic cup. With Instructions.

Description

Generates both AC and DC. When the two brushes of the generator are put in the two ends of the commutator, the output is an AC. When the brushes are put in the middle of the commutator, the output is a DC. Includes Instructions.
