To distinguish between the conductors and insulators.
Kit contains five strips of different material (wood, acrylic, copper brass and aluminium), one lamp and one 9 V battery mounted on plastic base.
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.

A simple form of D.C. motor with 2 pole armature wound with insulated copper wire and a permanent magnetic field provided by a removable bar magnet with a commutator and phosphor bronze brushes connected to 4 mm sockets, open construction, all parts visible.
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.
This heavy duty demountable transformer can be used for the study of transformertheory and many other alternating current phenomena.
This kit consists of:
1. A magnetic circuit made of highly permeable U shape metal sheet, which can be closed using two clamps with tightening screws.
2. Section: 40 x 40 mm with 150 mm length and 170 mm height.
3. One coil of 6000 turns with maximum current of 0.2 A. Intermediary coil of 2000 turns output.
4. One coil of 600 turns with maximum current of 2.5 A, which is mainly used to create the primary of transformer.
5. One coil of 1200 turns with maximum current of 1.25 A, fitted with intermediary 400 and 800 turns outputs.
6. One coil of 72 turns with maximum current of 12 A, fitted with intermediary 6, 30, 54 and 66 turns outputs.
7. Power supply cable.
The dynamo model is mounted on a base with a driving wheel.
Output is through 4 mm sockets and a low voltage bulb is also provided as a simple output indicator.
For Westminster Electromagnetic Kit giving 1 V full wave rectified DC and 1 V / 2 V AC outputs at 8 A max.
The circuit diagram is printed on the top panel which also carries mains switch, light indicator and output sockets for DC and AC With 1.5 meter mains detachable cable.
