Which common factor affects both resistance and resistivity and how?
Temperature is a common factor that affects both resistance and resistivity. As temperature increases, the resistivity of conductive materials typically increases due to increased atomic vibrations, which impede the flow of electrons. Consequently, this rise in resistivity leads to an increase in resistance for a given material. Thus, both resistance and resistivity are influenced by temperature, impacting the efficiency of electrical conduction.
What physical properties may change resistivity?
Resistivity can be affected by several physical properties, including temperature, impurities, and structural defects within a material. As temperature increases, the resistivity of conductors typically rises due to increased atomic vibrations that hinder electron flow. In contrast, semiconductors may exhibit decreased resistivity with rising temperature due to enhanced carrier mobility. Additionally, the presence of impurities or defects can disrupt the lattice structure, leading to changes in resistivity by altering the number of charge carriers or scattering mechanisms.
What will happen to the kinetic energy of gas molecules trapped in a rigid container if the temperature is increased?
increased
Five factors that affect resistance?
Electrical Resistance depends on three factors: Resistivity; Area; Length.Resistivity is the property of the matter. More Resistivity means more resistance.More Area means less resistance.More length means more resistance.R= Resistivity. Length/Area
Is resistivity of a conductor temperature dependent?
A perfect insulator has infinite ohms of resistance.

If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is decreased?
The resistance of a conductor is directly proportional to the resistivity of the conductor. since the resistivity of a conductor is decreases with decrease in temperature hence the resistance.
When a sample of germanium and silicon having same impurity density are kept at room temperature then resistivity of both?
The resistivity of germanium will decrease with increasing temperature due to a positive temperature coefficient of resistivity, while the resistivity of silicon will increase with increasing temperature due to a negative temperature coefficient of resistivity. At room temperature, silicon will have a higher resistivity compared to germanium.

When the length is increased 2 times the value for resistivity will be?
The value for resistivity will remain unchanged (provided temperature remains constant). Resistivity is a property of the material. The resistance, however, will double. Remember that resistance is directly proportianal to the length of the conductor and inversely proportional to the cross-sectional area of the conductor.
What is the difference between metal and semiconductor?
A semiconductor's resistivity decreases with increasing temperature. A metal's resistivity increases with increasing temperature.
The resistance of a wire depends on the?
The length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.
What happen to the speed if the particles if the temperature is increased?
It increases.
What will happen to the pH if the temperature is increased?
Nothing if nothing evaporates.
What will happen to the kinetic energy of gas molecules trapped in a rigid container if the temperature is increased?
increased
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.
What must happen for a superconductor to work?
Super conductor will have zero resistance or zero resistivity. This happens when the temperature of the conductor reaches a very low temperature known as critical super conducting transition temperature. In case of mercury it will be 4.2K.
