Our collection of electricity components, show higher stability with paper and electrolytic capacitors. The main items of this collection are capacitance boxes. Each decade is connected parallel having switch position of 0 to 10 and are mounted in line with 4mm socket terminals, which are linked to each inter decade junction & to the ends of the chain. Further, each earth terminal is connected to the metal case. Each of the top panel is precisely marked with the internal connection arrangement with overall tolerance and the highest safe current capacity. The entire capacitance box is housed in robust metal case. Another type of electricity components of our collection are Rheostat, Single tube protected variable can be found up to 345 ohms at 1.2 A rating. These are used as series resistors or as potentiometers. These are available in enclosed type within metal case of porcelain or windings.
