What is a material that loses its resistance to electrical flow at very low temperatures?
A material that loses its resistance to electrical flow at very low temperatures is called a superconductor. This phenomenon is known as superconductivity, where the material exhibits zero electrical resistance below a critical temperature.
What is the measure of how difficult it is for charges to flow through a material?
The measure of how difficult it is for charges to flow through a material is called electrical resistance. It is quantified in ohms and is determined by factors such as material composition, dimensions, and temperature.
The property of a conductor that impedes the flow of charge is called?
The property of a conductor that impedes the flow of charge is called resistance. It is measured in ohms and depends on factors like the material, dimensions, and temperature of the conductor.
What is the name for a material that has high resistance?
The material is called a insulator. It has high resistance to the flow of electric current.
What material has no electrical resistance?
Superconductors have no electrical resistance when cooled below a certain temperature, called the critical temperature. At this temperature, electrons can move through the material without any hindrance, allowing for the flow of electricity without any loss of energy.

What is the temperature coefficient of resistance?
The temperature coefficient of resistance is a number used to predict how the resistance of a material changes with changes in temperature. Typically the units are either resistance per temperature or 1/temperature depending on which equation is used for the calculations. For example, in copper the temperature coefficient of resistance is about 0.0039 per change in degrees Celsius. A positive temperature coefficient of resistance means that the resistance of the material will increase as temperature increases. As per the equation or say unit of resistance temperature coefficient, its definition can be given as below: " Rise in temperature per unit initial resistance, when temperature is raised by one degree Celsius is called the resistance temperature coefficient."

The opposition to the movement of charges flowing through a material is called what?
The opposition to the movement of charges flowing through a material is called resistance. It is a property that determines how strongly a material resists the flow of electric current.
What factors contribute to the electrical resistance of a conductor?
1) What materials the conductor is made of;2) the average cross-sectional area along the length of the conductor;3) the temperature of a conductor also affects its resistance;4) the length of the conductor is also very important.Generally, the longer the conductor, the higher its resistance.Your students' course materials can probably give you a better answer than mine, or at least you'll know it is the right one.The length, the cross sectional area, temperature of conductor along with the intrinsic property called the specific resistance of the substance.

Superconductors have no electrical resistance when cooled below a certain temperature, called the critical temperature. At this temperature, electrons can move through the material without any hindrance, allowing for the flow of electricity without any loss of energy.
What does resistance in wire depend on?
Resistance is directly proportional to the resistivity and length of the conductor, and inversely-proportional to its cross-sectional area. As resistivity is affected by temperature, we can say that temperature indirectly affects resistance.
What is the opposition to flow of electric charge?
The opposition to the flow of electric charge is called resistance. It is measured in ohms and can be influenced by factors like the material of the conductor, its length, cross-sectional area, and temperature.
What is pyroelectricity?
An element which displays electricity with change in temperature is called pyroelectric element.
Why a superconductor has no resistance at low temperature?
Superconductors have no resistance at low temperatures because electrons form pairs called Cooper pairs, which move through the material without scattering. This lack of scattering means the electrons can move without resistance, resulting in zero electrical resistance.
