Decade resistor, Physics

DECADE resistors are wire wound resistors. These are wound on cards moulded on round a switch of low contact resistance. Alloys used for wire are Manganin, minalpha, etc. Bifilar winding is used for winding on silk covered on metal-bobbin. Silver solder is used to connect the coils to strong connecting rods. The whole assembly is surrounded by a brass case. The values are 0.1, 1, 10, 100 ohms, 10 kilo ohms etc.
