It consists of a wooden base fitted with 4mm socket terminals, single wire and a 100cm wooden scale. Supplied without jockey.

It consists of nickel plated brass strips and connecting pieces with 4mm socket terminals, fitted on wooden base. Length 100cm long with plastic scale. Supplied without jockey.

It is used for investigating resistivity. The board is fitted with 4 mm terminals connected to a length of resistance wire which runs along a scale. Three different resistance wires with ratios of cross sectional area 1:2:4 (approx.) are provided. Sockets are provided on it so that the board can be used as a 40 cm bridge or potentiometer.

It is used to determine variation of resistance of a conductor with changes in length, material, diameter and the effect of series and parallel combination of resistances, this item is used. Ohm's Law may also be studied. The whole unit is mounted on a sheet-metal base, size: 12.5 x 110cm. There are 4 nos. of separate wires having length of 1 m each. The wires are constantan 24 swg, constantan 30swg, iron 30swg and Copper 30 swg. Each wire may be attached separately to binding posts. Ohm's Law may also be studied with the help of DC power supply and multimeters.

It consists of a metal base fitted with 4mm socket terminals, Supplied with jockey.

For use with Meter Bridge Carey Fosters and potentiometer work. Provided with locating notch in the plated Brass contact. 4mm socket is present on the brass terminal.
