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.

∙ 13y agoIn 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...

∙ 13y agoYes, 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.

∙ 10y agoConductors 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.

∙ 14y agoInsulators 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.
Wiki User
∙ 13y agoYes , conductor have low resistance ,current flows in the conductor due to low resistance.
Wiki User
∙ 13y agoYes 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.
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.
What type of current only consists of direct current at a low voltage and high amperage?
battery
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
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 Thermal conductors?
have high conductivity; have low specific heat
Why are acidic liquids good conductors?
Acidic liquids are good conductors due to the high concentration of hydrogen ions (H+) which can move around the liquid, carrying the electric current between the positive and negative electrodes. Acids have a low pH value and a high concentration of H+ ions.
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).
List of good and bad conductor of electricity?
Good conductors conduct electrical current very easily because of their free electrons. Some common good conductors are copper, aluminum, gold, and silver.Bad conductors (or insulators) oppose electrical current and make poor conductors. Some common insulators or bad conductors are glass, air, plastic, rubber, and wood.Conductors have a very low resistance to electrical current while insulators or bad conductors have a very high resistance to electrical current.
What is the difference between a high Nile and low Nile?

What are the electrical properties?

Why does sparking occurs in high tension conductors?
ya its very simple. Due to the high potential, there is a greater electric field developed around the conductors. This field ionizes the air present around the conductors. Due to the air to being ionized, the current wants to flow around it. So the sparking occurs. Which is actually the form of current.
