High resistance in earth-continuity conductors can primarily be attributed to poor connections, corrosion, or degradation of the conductor materials. Additionally, the use of inadequate conductor size or type can lead to increased resistance. Environmental factors, such as moisture and soil conditions, can also contribute to resistance, affecting the overall effectiveness of grounding systems. Lastly, long conductor runs can introduce additional resistance due to the length of the path.

Do most conductors have a inconstant resistance regardless of the applied voltage?
Most conductors exhibit a constant resistance within a certain range of applied voltage and temperature, following Ohm's Law (V = IR), where V is voltage, I is current, and R is resistance. However, at very high voltages or temperatures, some conductors may experience changes in resistance due to factors like heating or non-linear effects. Therefore, while they generally maintain constant resistance under normal conditions, deviations can occur under extreme circumstances.
Do conductors have high or low current?
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.
What are the names for high voltage power cables?
Electrical conductors
What causes high resistance in phone line?
High resistance in a phone line can be caused by various factors, including corrosion of the wire connections, damaged or degraded insulation, and physical wear and tear on the cables. Additionally, poor-quality materials or improper installation can contribute to increased resistance. Environmental factors such as moisture or extreme temperatures may also lead to deterioration, further increasing resistance levels.
What is excessive electrical resistance?
High resistance means insulation
What shows how conductors insulators superconductors and semiconductors rank in order of least resistance to most resistance?
Superconductors have no resistance, making them the best conductors. Semiconductors have moderate resistance. Conductors have low resistance, making them better conductors than insulators, which have high resistance, making them the poorest conductors.
What is conductors insulators superconductors and semiconductors rank in order of least resistance to most resistance?
Superconductors have no resistance. Conductors have low resistance, semiconductors have intermediate resistance, and insulators have high resistance.
Which has a higher resistance insulators or conductors?
No, the resistance of an insulator is very high.
Why do conductors have high resistance?
Conductors have high resistance due to their material properties. Materials with high resistivity like copper or aluminum impede the flow of electrons, causing resistance. Additionally, impurities and defects in the conductor's structure can also contribute to higher resistance.
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.
Do conductors or insulators have a lower resistance?
Conductors have lower resistance compared to insulators. Conductors allow electric current to flow easily due to the presence of free electrons that can move through the material, while insulators have high resistance as they do not allow the flow of electric current easily.
Why do spark plug wires have resistance?
All wires have a resistance, as does everything else in the universe. Conductors like metal and carbon generally have low resistances where as non conductors have a very high resistance. Think of it like friction, but electric.
What are 4 bad conductors?
Some examples of bad conductors of electricity include rubber, plastic, glass, and wood. These materials have high resistance to the flow of electric current, which makes them poor conductors.
What is the factors on which resistance depend .and explain?
Resistance depends on the material of the object (e.g. conductors, insulators), its dimensions (length, cross-sectional area), and temperature. These factors influence the flow of electrons through the material, impacting how difficult it is for current to pass through. Conductors have low resistance due to high electron mobility, while insulators have high resistance due to low electron mobility.
What are four bad conductors?
Rubber, wood, plastic, and glass are examples of materials that are poor conductors of electricity. These materials have high electrical resistance, preventing the flow of electricity through them.
What is the difference between isolators and conductors?
Isolators are materials that do not easily allow the flow of electricity, while conductors are materials that readily allow the flow of electricity. Isolators have high resistance to the flow of electrical current, while conductors have low resistance. Examples of isolators include rubber and glass, while examples of conductors include metals like copper and silver.
Can something be an insulator and a conductor?
No, a material cannot be both an insulator and a conductor at the same time. Insulators have high resistance to electrical flow, while conductors have low resistance.
