This resistance may then be combined with a third one by the same
formula, and thus any number may be calculated.
Synonym--Shunt Circuit.
Circuit, Voltaic.
Properly a circuit including a conductor and voltaic couple.
It is also applied to the electric circuit, q. v., or to any circuit
considered as a bearer of current electricity.
Circular Units.
Units of area, usually applied to cross sectional area of conductors, by
whose use area is expressed in terms of circle of unit diameter,
usually a circular mil, which is the area of a circle of one-thousandth
of an inch diameter, or a circular millimeter, which is the area of a
circle of one millimeter diameter. Thus a wire one-quarter of an inch
in diameter has an area of 250 circular mils; a bar one centimeter in
diameter has an area of ten circular millimeters.
[Transcriber's Note: Area is the diameter squared. A 1/4 inch wire has
62500 circular mils of area. A one centimeter (10 millimeter) wire has
100 circular millimeters of area. Actual area = circular mils * (PI/4).]
Circumflux.
The product of the total number of conductor turns on the armature of a
dynamo or motor, into the current carried thereby. For two pole machines
it is equal to twice the armature ampere-turns; for four pole machines
to four times such quantity, and so on.
Clamp.
The appliance for grasping and retaining the end of the rod that holds a
carbon in the arc lamp.
Clark's Compound.
A cement used for the outside of the sheath of telegraph cables.
Its formula is:
Mineral Pitch, 65 parts.
Silica, 30 parts.
Tar, 5 parts.
All parts by weight.
