Wheatstone Bridge, Two Gap
Comprising a resistance wire (SWG 26) stretched along a meter scale subdivided in mm and marked every cm. is clamped to stout brass plates so as to avoid end errors. A plated brass strip with 4 mm socket terminal is fitted along the meter rule to provide a two-gap system for normal Wheatstone bridge work. Complete with jockey.

Wheatstone Bridge, Four Gap
Four gap systems, enabling two additional resistances to be interpolated in the additional gaps, enable greater accuracy of measurement by reducing unwanted resistance to a minimum. Two brass strips are provided to close the gaps when so required. Complete with jockey.

Slide Wire Wheatstone Bridge
Consists of a resistance wire with a sliding contact and a strip of aluminum to provide two “arms” of the bridge for known and unknown resistance. Strips of heavy aluminum are provided with a single gap in each of two arms for the resistance. All components are mounted on a heavy sheet metal base. With Instructions.

Resistor Set
Consisting of six resisters of resistances with different current ratings. The resistors can be used in either the series or parallel mode. The resistors can be connected to any of the desired circuits through the safety sockets provided on the top of the kit for each resistor separately. Accuracy ± 5%. The specifications of each resistor are printed on the top panel of the kit. Mounted in moulded box.

Resistance Box
Resistance Box kit is an excellent device, which provides a very good learning technique in making different combinations of resistances, either in series or in parallel; or in both ways, to obtain the desired value of resistance for any circuit application. It consists of 10 resistors of equal values, 10 Ω, 2 W. These resistances have ± 1% tolerance.
