If the length of the conductor increases while the cross-sectional area remains unchanged, the resistance of the conductor will increase. This is because resistance is directly proportional to length according to the formula R = ρ * (L/A), where ρ is the resistivity of the material, L is the length, and A is the cross-sectional area.
If the length of the conductor increases while the diameter remains constant, the resistance of the conductor will increase. Resistance is directly proportional to the length of the conductor, so a longer conductor will have higher resistance. The diameter, however, does not directly affect resistance as long as it remains constant.
Skin is typically a poor conductor when wet due to its high resistance, which inhibits the flow of electricity through the body. However, if the skin has any cuts or breaks, it can become a better conductor, potentially leading to electric shock.
Air can become a good conductor when it is ionized, meaning its atoms and molecules become charged. This can happen due to high temperatures, exposure to radiation, or electrical discharges like lightning. When air becomes a good conductor, it allows electricity to flow easily through it, leading to phenomena like lightning strikes and electrical arcs.
If a very large electric field is applied on a conductor then a phenomenon of a dielectric breakdown takes place and it looses all its charge carriers to the nearest conductor. Hence becoming an insulator.

You become stronger.
Actually, it depends on the resistance of the other components in the circuit, and not so much on whether or not the total circuit current is low or not. Often, conductor resistance is ignored because it is so much lower than the active components that it does not matter. In a circuit with low resistance components, however, conductor resistance can be important, even if the total current is relatively low, because the voltage drop over the wire becomes a significant part of the overall circuit. To answer the specific question, even though its slightly misleading, conductor resistance does tend to become important in high current circuits because the voltage drop over the conductor (Ohm's Law: Voltage is current times resistance) can become high. Even in high current circuits, however, if the conductor is substantially less resistive than the components, the tendency is still to ignore it, except that you have to account for heating of the conductors along with heating of the components.

Unchanged. The conductor's ampacity is affected by its composition (copper, aluminum, etc.), cross-sectional area, and temperature, not by the supply voltage. The ampacity is limited because any conductor has resistance. When the conductor carries a load (supplies current), the conductor essentially becomes a resistance heater, and gets hot. At some point the temperature will become dangerous, either causing the conductor to melt or damaging the insulation or surrounding materials. The voltage dropped across a conductor that is supplying current to a load is computed by the following formula: E=I^2 X R Or, voltage dropped equals current through the conductor squared times the resistance of the conductor. Notice that the supply voltage is not even part of the equation. All the mentioned parameters - composition, cross-sectional area, and temperature affect its resistance. The ampacity of a conductor installed in a building can also be regulated by law, so, even though a conductor may pass a certain amount of current local laws may prohibit it's use anyway.
At ordinary temperatures, the element that's the best conductor of electricity is silver, with the second best being copper. At very low temperatures, some materials become superconducting. Superconducting materials are all perfect conductors of electricity, with no resistance at all.
when light falls on the it its electrons become excited and become free for conductivity that's why selenium is a photo conductor
If a very large electric field is applied on a conductor then a phenomenon of a dielectric breakdown takes place and it looses all its charge carriers to the nearest conductor. Hence becoming an insulator.
Some metals become a super conductor when you freeze them
Graduate and first aid certificate after this you have to take conductor training for two days for conductor certification from any IDTR center and after this you can apply in License Authority for conductor license
Paper is generally not a good conductor of electricity due to its high resistance. However, paper can become conductive when it is coated with conductive materials like graphite or silver ink. Overall, paper is considered to be an insulator rather than a conductor.
