What are the main causes of high resistance in the earth-continuity conductors?
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.
State the factors affecting resistance of materials?
The resistance of materials is primarily affected by temperature, material composition, length, and cross-sectional area. As temperature increases, resistance typically increases for most conductors. Additionally, materials with higher resistivity, such as insulators, exhibit greater resistance. The length of the conductor directly impacts resistance, with longer materials having higher resistance, while a larger cross-sectional area reduces resistance.
The relationship between resistance and conductors is?
ALL resistance are conductors. just the magnitude value changes
What is the characteristic of a material that hinders electron flow?
It is called resistance Good conductors have a bad resistance While bad conductors or insulators have good resistance against the flow of electricity
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.

What are the factors affecting the environmentel resistance?
The availability of food is an example of a factor that affects environmental resistance. Other factors include climate and predators.
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.
Factors affecting resistance of a metal conductor?
The material, the length, the cross section.

What are the factors that affect resistance?
The factors are: length, cross-sectional area and nature of substance.
What are the factors affecting movements?
1. Friction 2. Wind resistance 3. Velocity
What are the two factors affecting air Resistance?
The two factors affecting air resistance are the speed of the object moving through the air and the cross-sectional area of the object. Faster speeds and larger surface areas create greater air resistance, slowing down the object's motion.
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 the factors affecting the resista nce of a wire?
The factors affecting the resistance of a wire are its length, cross-sectional area, resistivity of the material, and temperature. As the length of the wire increases, the resistance also increases. A larger cross-sectional area decreases resistance, while higher resistivity materials and increased temperature contribute to higher resistance.
