With driving wheel, to generate current, mounted on polished wood base with driving wheel in vertical position, a lamp holder and a lamp.
Output DC Current
Output both DC and AC current
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.
For use on double 'C' core, wound with 1,100 turns of 22 swg copper wire with a resistance of about 6 ohms and inductance of about 15 henries, size 100 x 60 x 55 mm approx.
Wound on rectangular bobbin, for use with 220 – 240 V AC mains with detachable mains connector with moulded plug, A 4 mm socket is provided for earthing.
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.
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.
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.
