How do you calculate diameter of a copper wire conductor and how do we calculate resistance of a copper wire conductor of a particaular length?
You go to the NEC and look at the chart for developed length and the ambient temperature and the load factor and if it solid or stranded wire as stranded allows for more voltage
Why is the grounding conductor flat?
When stranded conductor is being used for earthing, It offers some reactance in addition to the resistance of the conductor. Since any kind of surge is of sudden in nature, and reactance opposes the change in flow of current (Property of Inductor), It might disturb the discharge rate of the surge. Hence the conductor is flat inorder to provide only the resistance
Some organisms use single-stranded rather than double-stranded DNA In these organisms which enzyme would probably not be needed for DNA replication?
DNA helicase
When a restriction enzyme cuts a dna molecule the cuts are staggered so that the dna fragments have single stranded ends why is this is important in recombinant dna work?
It is important because the fragments will bond to other fragments with complementary single-stranded ends.
Does viruses contains genetic material?
All viruses have genes made from either DNA or RNA but they themselves don't have DNA. (Viruses use tRNA or mRNA or DNA as a tool for infecting host cells, but they they do not use either for their own internal bio-mechanics)

True or false stranded wire has a slightly smaller diameter than solid wire?
They should be the same but have different purposes. Stranded wire will flex easier than solid wire. And if one strand breaks there are sufficient numbers of other strands to continue the electrical current. When a solid wire breaks all connection is lost.
What is the advantage of using a stranded copper conductor over a solid copper conductor?
It would of course depend on the specific application. Current tends to travel on the surface of a conductor and a stranded conductor has more surface area and thus offers less resistance to the current. Stranded wire also bends a bit easier than the corresponding size solid wire.
How are electrical wire sizes measured?
The amperage capacity of a wire is determined by the cross sectional area of the wire.Another AnswerElectrical conductors are expressed in terms of their cross-sectional area. In Europe, for solid conductors, this is expressed in square millimetres. Stranded conductors are expressed in terms of the number of strands, and the diameter (in millimetres) of each strand, expressed in the format A/B (where A = number of strands, and B = diameter of strand) -from which the total area, in square millimetres can be determined.In North America, the cross-sectional area is expressed in circular mils (round conductors) or square mils(rectangular conductors). A 'mil' is one-thousandth of an inch. A 'circular mil' is the diameter of a conductor, expressed in mils, squared -so it is not really a measure of area (as it doesn't take pi into account), but a figure that represents an area.
Is stranded copper wire a better conductor than solid copper wire?
no
What is rm of cable?
RM-Conductor of Multiple stranded wires of circular cross section.
Why is speaker wire stranded not solid?
high frequencies utilize the skin effect, running on the exterior of the conductor, with low frequencies utilizing the core of the conductor. Stranded wire has more skin area and would enhance higher frequencies, while solid wire would enhance lower frequencies. stranded is more flexible
Difference between solid and stranded conductors?
In a solid conductor there will be only one conductor ,but in stranded conductors there are several conductors twisted together to make a whole conductor ,this is mainly done to increase flexibility of the Conductor .
What is NS stand for on Wire rolls?
Probably "non-stranded" ... the wire is a single solid conductor, not a bundle of much thinner wires.
Why are appliances cord made of stranded wire?
Appliances cords are made of stranded wire because it is more flexible and less likely to break than solid wire. The multiple strands of wire in a stranded conductor also make it more resistant to fatigue and bending, which is important for a cord that may be moved and adjusted frequently.
What do you do in Club Penguin when you are stranded?
stranded where? stranded where? stranded where?
What are the differences between THHN solid and stranded wires?
THHN solid wires have a single, solid conductor, while THHN stranded wires have multiple smaller strands twisted together. Solid wires are more rigid and better for long runs, while stranded wires are more flexible and better for applications that require frequent bending.
