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.

What is Charles Jourdan known for designing?
Charles Jourdan who lived from 1887 until 1976 was a French fashion designer. He is best known for using innovative materials in the women's shoes which he designed.
Can uninsulated wire be used in place of enamel wire?
Depends on what you are using it for:short point to point connection - yes, usually but be careful to avoid shortscoil winding - NO NO NO, the coil will be completely shortedgeneral wiring - NO NO NO, use hookup wire instead as the enamel is too fragile
Could using old electrical cords cause a short circuit?
They could if they have cuts in the outer layer of insulation. The outer sheath of the cord is what is used to protect the inner conductors of the cord. Any damage to it should be repaired immediately. A properly maintained electrical extension cord should give years of service.
Whats the main difference between small signal amplifier and large signal amplifier?
1.Small signal amplifier can be designed easily using s parameter while large signal amplifier not.
How does a kitchen foodsaver work?
A kitchen foodsaver works by preserving the life of meats, vegetables, and other foods. This is done by placing foods in a specially designed plastic bag and using a machine to vacuum seal all air from the bag.
How can one effectively embrace and enhance the beauty of silver strands in their hair?
To effectively embrace and enhance the beauty of silver strands in your hair, consider using purple shampoo to prevent yellowing, using a hydrating hair mask to keep hair healthy, and getting regular trims to maintain a polished look. Additionally, consider using styling products specifically designed for silver hair to enhance shine and vibrancy.
Why are switches and electric sockets are made by using conductors?
They are made using both conductors and insulators: conductors where you do want the electricity to be able to flow and insulators where you want to prevent the electricity from flowing.If they were made using just one or the other, they could not perform their intended functions.
Could you build a working electric circuit using glass rods as the conductors why or why not?
Could you build a working electric circuit using glass rods as the conductors? Why or why not?
How is the low tensile strength of aluminium compensated for in the construction of overhead lines?
Aluminum conductors used in overhead lines are often larger in diameter to increase strength. Additionally, reinforcing strands or steel cores can be added to provide extra support. The design of the transmission towers also plays a role in distributing the load and reducing stress on the conductors.
Using super conductors to build computers is an example of?

DNA fingerprinting involves cutting DNA strands using which what?
Restriction enzymes
Did Brian designed an arrow that would fly correctly by making it shorter Hatchet?
Yes, Brian designed a smaller arrow by shortening the shaft and using bird feathers for fletching to ensure it would fly correctly in "Hatchet."
What are the uses of super conductors?
Super conductors would have zero resistivity. Hence no loss due to joule's heating. So power transmission could be done with larger efficiency. Strong electric current could be passed without hesitation due to zero resistance. Hence intense magnetic field could be produced. With this levitation of trains above the rails and hence fast movement of trains. With magnetic propulsion technique satellites could be launched without using rockets. In computers for storing a vast memorable information super conductors could be used. Even generators of several mega watts but of smaller size could be designed.

How can I efficiently shuffle small cards using a card shuffler designed for smaller cards?
To efficiently shuffle small cards using a card shuffler designed for smaller cards, follow these steps: Place the small cards into the card shuffler according to the manufacturer's instructions. Ensure that the cards are evenly distributed within the shuffler. Activate the shuffler to thoroughly mix the cards. Remove the shuffled cards from the shuffler and they are ready to use.
What are some advantages to using super-conductors as electric transmission lines?
Super-conductors have zero electrical resistance, allowing for highly efficient electricity transmission over long distances without energy loss. They can carry much higher amounts of electricity compared to traditional copper wires, potentially reducing the need for multiple transmission lines. Super-conductors also require less maintenance and have a smaller footprint, making them suitable for urban areas.
What is the likely effect of reducing the number of strands in a conductor if it is difficult to insert into a terminal?
If you're talking about removing actual strands, you'll lose current carrying capacity and could potentially fry the connection. If you're talking about reducing the number of strands and using larger strands, you won't help your situation or could make it worse.
