That depends on the metal composition of the wire, the diameter of the conductor and the amount of energy being applied. In general though a stranded wire of the same composition as a solid wire does not have more resistance.

What experiments suggest that wires have essentially zero resistance?
Think of this as two scenarios. First, we have one blub, one battery, and two wires in a closed circuit, and the bulb lights up. Next, think about what would happen if we added a couple more wires to the circuit. The bulb would still light up, just as brightly, meaning that the new wires are not increasing the amount of resistance. This means that the wires are not slowing down the flow of charges.
If two wires of the same material have the same thickness but different length the blank wire will have greater resistance?
The thinner the wire, the higher the resistance. The thicker the wire, the resistance decreases. Think of it this way. The thick wire has more room for electrons to jump around, but the thin wire has less room.
Why does a long and thin wire have a great resistance?
Because resistance is inversely proportional to the cross sectional area of the wire and directly proportional to its length. R = p*L/A, where R is resistance (in Ohms), p is resistivity (property of the material, in Ohms*m), L and A are length and area of the wire. And if you think about it, it makes perfect sense. In thick wire electrons have a lot of 'room' to move, they do not obstruct the path. If you imagine it is like a road with many free lanes - cars move fast and freely i.e. low resistance (or more scientifically, like many wires in parallel). Where as length is proportional to the resistance, since every small segment of wire adds more resistance to the total (many wires in series).
Is a conducting material used within flexible wires metal?
yes it is Conductors for flexible wires are normally made of stranded copper. Stranded conductors are composed of uninsulated "strands" of wire twisted together. The advantages of stranded conductor over a single strand of equal cross-section are increased flexibility and flex-fatigue life. The more strands of fine wire, the more flexible the wire will be. Other conductor materials include:aluminum and stainless steel. For more unusual applications, conductors are fabricated from pure nickel, pure silver, copper-covered aluminum, and a host of metals, metal alloys, and metal combinations. Metalized fibers such as Aracon can also be used for conductor material. Insulation also plays a role in a wire's flexibility.
Which has greater resistance a thick wire or a thin wire of the same lenght?
The thin wire has more resistance to the flow of electric current than the thick wire. If you connect the wires to a battery the battery will supply electrical pressure (voltage) and the wires serve similar to pipes that conduct water under pressure. A small pipe exhibits more resistance to the flow of water and a thin wire exhibits more resistance to the flow of electrons. However, as you point out different wire materials exhibit different resistances for equal sizes (silver conducts better than copper, etc.).
What is the advantage of stranded wires?
Flexibility is the main advantage of stranded wires; however for high frequency AC (i.e. radio frequencies), stranded wires increase the surface area, minimizing the skin effect (i.e. high frequency current avoiding the core of a wire, increasing its resistance at that frequency). This is not an issue at typical power frequencies (e.g. 60Hz) as the skin effect is still insignificant at those frequencies.
What are the Advantages of bundle conductors over solid conductor?
By bundle conductors, I am assuming that you mean stranded conductors. If you actually mean bundles of wires, then the bundles could be either stranded or solid and your question does not make sense. Stranded conductors have two main advantages over solid conductors. The first is flexibility. Stranded conductors are much more flexible than their solid counterparts. The second main advantage is skin surface area. Alternating current tends to travel towards the outer skin of a conductor. This is known as the skin affect. Stranded wire has a lot more skin surface area than solid wire does. There may be more advantages, but these are the two I could think of off the top of my head.
Why are automotive wires stranded?
For reducing the resistance for any given length two wire in if parallel will have reduced resistance. And for manageabilityAnswerIt makes cables more flexible.
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.
WHY STRANDED CONDUCTERS ARE USED IN POWER CABLES?
Stranded conductors are more flexible than solid conductors.
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
What is the meaning of solid wire?
Wire can be fabricated in two different forms. Solid wire refers to a single wire, while stranded wire is a wire which is made up of more than one single solid wire twisted together. A stranded wire is much more flexible, and less subject to breaking from flexing than a stranded wire of the same size.
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
Why conductors are designed using smaller strands?
Two reasons:Mostly a stranded wire is far more flexible than a solid one and less likely to break after repeated flexing.At AC frequencies in the RF range an effect called the "skin effect" starts to become significant, current flow restricts itself to the skin of the conductor and the wire resistance rises. Stranded wire offers more skin and thus reduces the wire resistance again.
How does the resistance differ between long and short wires?
Generally, the longer the wire, the more electricity will be lost because of resistance.
What solid and multi-stranded cables?
A given crosssection or diameter of the conductor can be obtained by a single strand wire or with many smaller diameter wires put together. For example a 4 sqmm wire can be one solid wire of 4sqmm or can comprise many smaller diameter wires twined together. A solid wire is more rigid whereas multistrand wire is flexible. A solid wire may not need a terminating lug, whereas a multistrand wire needs a terminal lug for termination / connection to a terminal block
Do thicker or thinner wires have more Resistance?
Over the same distance the larger diameter wire will have less resistance that the smaller diameter wire.
