Can an overhead conductor carry more current on a cold day as compared to a hot day?

The only limit on how much current the conductor can carry, regardless of
the weather, is the amount of current that causes the conductor to melt.
The current in such a conductor depends on the voltage between its ends,
and on the resistance of the conductor. The resistance of the conductor is
somewhat less when it's cold, so a given voltage would result in more current.

Is carbon an insulator or a conductor?
It depends on the type, or allotrope, of carbon you're talking about. For a material to conduct electricity, it should have free electrons to carry the electrical current. In diamond, an allotrope of carbon, there are no such free electrons. This means that diamond does not conduct electricity. However, graphite, another allotrope of carbon, conducts electricity very well because it has an entire "sea" of free electrons.
What is a machine that uses an energy source to produce electricity?
A generator generates electricity. A simple generator consists of a magnetic field, relative motion between the conductor and magnetic field, and a conductor to carry electrical current to the load. Turbines drive the generators to create the necessary relative motion utilizing steam or water as the prime mover.
What is the difference between sodium and sodium oxide electrical conductivity?
Sodium metal, in both its solid and liquid states, is a conductor. This is due to the delocalised 'sea' of electrons present in metallic bonded substances, which are able to carry and transfer current. Sodium oxide in its solid state is not conductive. This is because of its ionic bonded structure, in which sodium and oxygen ions are arranged in a continuous 3D structure, where they are fixed in place as an ionic lattice. However, in its molten state (or aqueous) the Na+ and O2- ions are free to move around, hence being able to carry current and thus conduct
When a river meets an ocean why do sediments drop out?
It will drop because there is no longer a current to carry the sediments.
Why can't sodium chloride conduct electricity in crystalline form?
Ionic compounds are unable to conduct electricity in crystalline (or solid) form because the ions are unable to carry the electric current since they cannot move from their fixed positions. When in a dissolved state, the ions separate and can thus carry the current.
What are the materials added in electrical overhead lines?
Overhead electrical lines are usually made of aluminum, and some have a steel strand added which is used to give the conductor more strength (not to carry current).
Can ground conductor use as a neutral conductor in a house wiring?
No. Absolutely not. The ground conductor is not rated to carry constant current flow. It is only rate to carry fault current flow.
What is the difference between a insualator and a conductor?
Conductor will carry current/insulator won't.
What is carry current?
the current carried by conductor, either static or motional
Electric current in a metal conductor is carried by?
Electric current in a metal conductor is carried by a wire. This wire has been specifically adapted to carry this current.
Which conductor do you use in overhead lines installation?
There are lots of choices for type of conductor - ACSR is a very common one. In my experience aluminum is the most often used metal. ACSR uses aluminum to carry the current, and also has a steel core that provides added strength.
Can current pass throug one thick conductor?
Wire is sized to carry current, it doesn't matter whether the voltage is AC or DC. The larger the diameter of the wire the more current it is allowed to carry.
Do copper carry current?
Yes, copper is a good electrical conductor.
Does copper wire carry electric current?
It is a conductor & common in wiring.
What is a material that will carry an electric current called?
A material that will carry an electric current is called a conductor. Conductor materials have high electrical conductivity, allowing the flow of electric charges with minimal resistance. Examples of conductors include metals such as copper, aluminum, and silver.
What is the general name for the property of a material which enables it to carry an electrical current?
Conductor
Is salt a conductor or an insulator?
salt water is a good conductor of electricity as it contains sodium and chloride ions to carry out current
