Dissectible Transformer
Catalogue No: 1090160/1
For demonstration of basic concepts associated with electromagnetic induction such as AC transformers, induced currents and their effects etc. Comprises a U-Core and I-Core, made from high grade laminations to minimize the induction losses, I-core sitting completely over U-core to provide a continuous rectangular annular laminated block. Arms of the U-core takes various coils included for different experiments. All coils are wound from enameled copper wire on rectangular plastic bobbin and are totally covered to prevent any contact with the winding. 4mm sockets provided for connections except for 600 turns coil that operates on AC mains and is provided with a 3-pin AC MAINS socket. Each coil clearly marked with number of turns and sits comfortably on U-core arm without air gap. Also included is a pair of soft iron pole-pieces to sit on top of U-core arms. One end of each pole piece is flat so that the pole pieces in situ provide a narrow gap with full cross-sectional area, while the other end in form of truncated cone providing narrow concentrated field between the poles. Following components are included in the apparatus:
– Laminated U-Core: 1 No.
– Laminated I-Core: 1 No.
– Stand for Dissectible Transformer: Cast metal stand consisting of a stable, non-skid heavy base with two removable clamping arms at the top.
– Soft iron Pole Pieces: 2 Nos.
– One coil of 6000 turns, maximum current 0.2A with one intermediary output corresponding to 2000 turns.
– One coil of 600 turns, maximum current 0.25A. Mainly to create the transformer primary. Provided with mains power connection.
– One coil of 1200 turns, maximum current 1.25A, with intermediary outputs corresponding to 400 and 800 turns.
– One coil of 72 turns maximum current 12A, with intermediary outputs corresponding to 6, 30, 54 and 66 turns.
Complete with Instructions on how to perform various activities.

Potentiometer
Catalogue No: 1091140/4
Works on the principle of variation in the resistance of a conductor with length and useful as a potential divider for various electrical experiments such as in null point detection. Comprising a 24SWG bare constantan wire stretched along a meter rule (graduated in millimeters) and is clamped to brass plates. The clamping system is designed to make electrical contact with the wire at the exact ends of the scale thus virtually leaving no margin for “end errors”. The terminating strips are provided with heavy-duty 4mm socket terminals.

Wheatstone Bridge, Four Gaps
Catalogue No: 1091100/1
For determination of unknown resistances or comparison of resistances. This substantial FOUR-GAP bridge has heavily plated brass strips mounted on a base. Terminals with 4mm sockets are provided to reduce unwanted resistance to a minimum and the gaps are closed by removable brass strips, which are held in position by the terminals. The 24SWG bare constantan wire is stretched on top of meter scale along its length graduated in millimeter and figured at every centimeter. The ends of the wire are securely clamped to the terminating strips to reduce end errors to the negligible level. Wire easily replaceable if damaged or broken. Supplied with jockey.
