Low resistance.
Think of Ohm's law. Voltage drop is directly proportional to resistance. The higher the resistance, the higher the voltage drop, and the less voltage that is available for the load. Think of conductor resistance as a resistance in series with the load.
Also, higher conductor resistance means more power lost, going to heating the conductors. The "line loss" formula is P=I2R. The greater the resistance, the greater the electrical power being converted into thermal power heating the conductors.
In electronics, conductors have low resistance. They also tend to have low resistance to temperature change also.
Silver, copper, gold, aluminum are examples of both good thermo conductors and electrical conductors. That happens to be the list of the best electrical conductors in order...

Yes, all conductors have some amount of resistance although it varies depending on the material that is conducting the electricity.
Copper has a very low resistance, and aluminum has a slightly higher (but still quite low) resistance. This is why they are used as electrical conductors.
Conductor resistance results in voltage drop over the conductor and power loss, manifested as heating of the conductor. Therefore, you want as low a conductor loss as is reasonably practical.
The reason of resistance is that, no electron has a linear motion when an electric field is applied to it. e- move in random due to apparent collision with other e-'s. This motion is termed to as Brownian motion. The random movement however interrupts with the electric field and creates resistance sue to a negetive field generated.
Conductors have low electrical resistance.
Using Ohms Law resistance (ohms) equals V/I or volts per ampere. The greater the resistance the more voltage required to produce a given current.
Conductivity on the other hand is I/V or amps per volt. The greater the conductivity, the more current produced for a given voltage.
Insulators are the materials having very high resistance. No current flows through the insulator.mica, ceramic, wood, glass are some of the examples of the insulators.
Yes , conductor have low resistance ,current flows in the conductor due to low resistance.
Yes they do, as they need lots of energy to be passing through them, they need to have a low resistance level.

What happens when you connect a low current device to a high current source?
The High current source otherwise known as the supply, can handle any low current device or low current load as long as the voltages are the same. The higher the Supply current or as you call the source the better for any device/load
What type of connection produce high current?
A device with a low resistive load will produce a high current in a series circuit.
Why are high voltage electrical distribution systems needed in a modern supply system?
For any given load, the higher the supply voltage, the lower the load current. So we use very high voltages on transmission/distribution lines in order for the load current to be low enough to enable us to use conductors of practical size. Furthermore, if we were to use low voltages, the resulting load current would be so high that there would be an absolutely enormous voltage drop -so much so that it would be impossible to transfer the required energy. Low currents also mean less line losses.
What type of current only consists of direct current at a low voltage and high amperage?
battery
Why do high tension transmission wires carry electricity at high voltages?
For a given load, the higher the supply voltage, the lower the resulting load current. So, using high voltages reduce the load current which, in turn:minimise voltage drop along the line (which, at low voltages, would otherwise be enormous, rendering transmission of energy impossible).enable conductors of practical size.reduce line losses.
How you understand which side of a transformer is high voltage side and low voltage side?
at high voltage side, current is low. hence the size of conductors is reduced or small. At low voltage side, current is high. Hence the size of conductors is large.
Good conductors have a high resistance or low?
Good conductors have low resistance. A low resistance allows for the easy flow of electric current through the material. Materials like metals are good conductors because they have many free electrons that can move easily in response to an electric field.
Is resistivity of a good conductor high or low?
The resistivity of a good conductor is low. Good conductors have a low resistance to the flow of electric current due to their high conductivity, allowing electricity to pass through easily.
How are materials classified on the basis of resistivity?
Materials can be classified based on their resistivity as conductors, semiconductors, or insulators. Conductors have low resistivity, allowing electric current to flow easily. Semiconductors have resistivity in between conductors and insulators, and their conductivity can be controlled. Insulators have high resistivity and do not allow electric current to flow easily.
HOw does electricity get transported and why does it need to be at a high voltage?
The primary reason that power is transmitted at high voltages is to increase efficiency. ... The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. And when resistance losses are low, energy losses are low also.
What is condutors insulator?
Conductors are materials that allow the flow of electrical current, such as metals. Insulators, on the other hand, are materials that do not allow the flow of electrical current, like rubber or plastic. Conductors have low resistance to the flow of electricity, while insulators have high resistance.
Does a good conductor has a high resistance?
No, a good conductor has a low resistance. Resistance is a measure of how difficult it is for electric current to flow through a material, and conductors allow electric current to flow easily.
What Thermal conductors?
have high conductivity; have low specific heat
How are substances classified on the basis of resistivity?
Substances are classified based on their resistivity as conductors, insulators, or semiconductors. Conductors have low resistivity and easily allow the flow of electric current. Insulators have high resistivity and inhibit the flow of electric current. Semiconductors have resistivity values between conductors and insulators, making them suitable for controlling the flow of current in electronic devices.
How much resistance do conductors have?
Conductors have low resistance to the flow of electric current. The resistance of a conductor depends on its material, length, and cross-sectional area. Materials like copper and silver have low resistance, making them good conductors of electricity.
Materials that allow current to move freely through them are called?
conductors. Examples include metals such as copper, silver, and aluminum. Conductors have low resistance, making them ideal for carrying electrical current.
What are conductors and insulators of electricity?
Conductors are materials that pass electrical current easily, that is, with low resistance. Insulators are materials that do not pass electrical current easily, that is, they have high resistance. Conductors are ordinarily metals, and insulators are ordinarily nonmetals. Some examples of conductors are: Silver, Copper, Carbon, and Aluminum. Some examples of insulators are Glass, Nylon, and Wood (as well as Air and Vacuum). Conductivity is a function of the mobility of Electrons in the materials in question. Conductors have high mobility and conductors have low mobility. Semiconductors are materials that have some properties of both conductors and insulators. Germanium and Silicon are well known semiconductors. Superconductors are materials that pass electrical current with zero resistance. All known superconductors perform this function only at very low temperatures, far below those encountered in Earth environments (i.e. from around 77 degrees above absolute zero down, or, in other words, below about -320 degrees F).
