Demonstration Dynamo
This model uses the same basic assembly as the electric motor, mounted on a base plate which also carries a hand drive pulley 120 mm in diameter coupled to the smaller dynamo pulley by a rubber belt. Electric output is via a pair of 4 mm socket & a light emitting diode is provided as simple output indicator. The model may also be used as motor on a 4 to 8 volts DC supply.
Demonstration Dynamo A.C.
A simple demonstration of a Dynamo Model mounted on a wooden base. Hand driven by a gear. Simplified open frame construction which can be readily understood without detriments to its essential similarity to real machine. A 2 pole armature wound by enamelled copper wire to rotate in U shape magnet in pivot. While in rotation process through the gear wheel by hand, the bulb provided glows.
Demonstration Dynamo D.C.
A simple demonstration of a Dynamo Model mounted on a wooden base. Hand driven by a gear. Simplified open frame construction which can be readily understood without detriments to its essential similarity to real machine. A 2 pole armature wound by enamelled copper wire to rotate in U shape magnet in pivot. While in rotation process through the gear wheel by hand, the bulb provided glows.
Demonstration Dynamo A.C. and D.C.
A simple dynamo model to differentiate AC from DC. Mounted on a wooden base. Two bulbs are provided for AC & DC current(s). The model is hand driven & when operated, the AC bulb shows flickering light to indicate AC current while the other bulb glows fully indicating DC current.
Lampholder
Suitable for mounting screw threaded type MES bulb. Round base with holes for screw mounting.
Leads
Insulated, PVC coated, with one end crocodile clip and at the other end banana plug.
Multimeter Digital LCD - Deluxe
DC voltage upto 1000 V in five ranges; AC voltage upto 750 V in five ranges; DC current upto 10 A in five ranges; AC current upto 10 A in five ranges. Resistance upto 200M ohms in seven ranges, with buzzer.
Coil 120 Turns
Each centre hole coil is wound on a plastic former & is provided with 4 mm socketed terminals.
The coil fits onto a double ‘C’ core, provides a suitable transformer
for operation from a low voltage AC supply. In addition, it provides a
useful electromagnet if used on one half of a ‘C’ core.
Coil 2400 Turns
Each centre hole coil is wound on a plastic former & is provided with 4 mm socketed terminals.
The coil fits onto a double ‘C’ core, provides a suitable transformer
for operation from a low voltage AC supply. In addition, it provides a
useful electromagnet if used on one half of a ‘C’ core.
Coil 240 Turns
Wound on a plastic bobbin to fit a standard ‘C’ core. The coil is centre hole & provided with 3 mm socketed terminals.
Electric Motor With Newtons Disc
Mounted on a wooden base 90 x 90 x 100 mm, workable on 2 to 4 volt DC with fan blade & Newton’s colour disc.
Multimeter Analogue
Low cost moving coil multimeter for AC/DC & resistance measurements, having a knife edge pointer moving over a two colour scale. With 175µA f.s.d. sensitivity. Range selection is by pins. Test leads stay firmly in the terminals. Two 1.5V batteries included.
Resistance Box
Resistance coil on a bakelite case round in shape with 2 terminals and value written on it.
