What else can I help you with?
What things heat up when electricity flows through them?
Materials with electrical resistance. The heating in any circuit element is by Ohm's Law given by (Current)2 x Resistance. Some materials like silver and copper have very low resistance so little heating.
What call materials with a resistance of 0?
Materials with zero resistance are called superconductors, which allow electrical current to flow through them without any loss of energy. Superconductors display this property at very low temperatures, reaching a state of zero electrical resistance known as superconductivity.
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.
What are the materials have low resistance?
Conductors.
Which element has the property of zero resistance?
The element that has the property of zero resistance is superconductors. Superconductors are materials that can conduct electricity without any resistance when they are cooled to very low temperatures.
What are the main materials from which alcoholic drinks can be made?
yeast, and i dont know any others lol
Do all conductors have resistance?
Yes, all conductors have resistance to some degree. Resistance is a property of materials that impedes the flow of electric current. However, some materials have lower resistance (e.g., copper) while others have higher resistance (e.g., rubber).
Why the nature of materials affect the resistance?
The nature of materials affects resistance because different materials have varying numbers of free electrons, which are responsible for conducting electricity. Materials with more free electrons, like metals, have lower resistance since electrons can flow more easily through them. Conversely, insulating materials have high resistance because they have very few free electrons available for conducting electricity.
What material does resistance depend on?
Resistance depends on the material's conductivity, temperature, and dimensions. Materials with high conductivity exhibit low resistance, while materials with lower conductivity exhibit higher resistance. Temperature can also affect resistance, with most materials experiencing an increase in resistance as temperature rises. Additionally, resistance is directly proportional to the length of the material and inversely proportional to its cross-sectional area.
What property of materials that slows the flow of electrons is?
The property of materials that slows the flow of electrons is resistance. Resistance is caused by the interaction of electrons with the atoms in the material, leading to energy loss in the form of heat. Materials with high resistance are poor conductors of electricity.
What word describes the Phenomenon when resistance of electricity stops at cold temperatures?
Superconductivity is the phenomenon where electrical resistance drops to zero at low temperatures. At these temperatures, certain materials can conduct electricity without any losses due to resistance.
What does it mean when a material is described as having a low resistance?
When a material has low resistance, it means that it allows electric current to flow through it easily. This is because low resistance indicates that the material offers little opposition to the flow of electrons. Materials with low resistance are commonly used in wires and electrical conductors.
