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.
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.
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.
Investigate the working principle of circuit breaker type fuse with this demonstration model.
The apparatus is built on a robust plastic base and includes resistive loads to simulate external wiring circuits.
Applications of the thermal response of bimetal strips and also electromagnetism (movement from a solenoid) are clearly demonstrated in this model.
When a 12 V DC supply is connected (not supplied) the LED lights to show that current is flowing in the external circuit and the bi-metal strip can be seen to bend as its heater coil raises the temperature.
After a few minutes the bending is sufficient to trip the mechanism and the current path is broken.
At any current selection a short circuit situation can be initiated by pressing the red button and this produces an immediate response from the solenoid to disconnect the supply.
