How does the type of the material affect resistance?
The type of material affects resistance because different materials have different inherent properties that determine how easily electrons can flow through them. In general, materials with higher resistivity will have higher resistance, while materials with lower resistivity will have lower resistance. Additionally, factors such as temperature and impurities in the material can also influence its resistance.
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.
How does the type of the material affect its resistance?
The type of material affects resistance because different materials have different properties that impact their ability to conduct electricity. Materials with high electrical conductivity, such as metals, have low resistance, while insulating materials like rubber have high resistance. This is due to the relationship between the material's atomic structure and how easily electric currents can flow through it.
What are three things resistance of a wire depends on?
The resistance of a wire depends on its length - longer wires have higher resistance. It also depends on the material of the wire - materials with higher resistivity have higher resistance. Lastly, the cross-sectional area of the wire affects resistance - larger cross-sectional areas have lower resistance.
Why the inductor heat up?
Temperature affects the resistivity of materials which, in turn, affects their resistance. For pure metal conductors, their resistance increases with temperature. As an inductor is often made from a coil of copper wire, its resistance will increase whenever its temperature increases. If it is important for the resistance to remain constant over a wide variation of temperature, then alloys, such as constantin, are used instead of copper. These alloys maintain an approximately-constant resistance over a wide range of temperatures.
What affects the electrical resistance of a body?
The electrical resistance of a body is affected by the material it is made of, its length, cross-sectional area, and temperature. Materials with high resistivity, longer lengths, smaller cross-sectional areas, and higher temperatures will have higher electrical resistance.

What affects the resistance of a conductor?
The length and the material that the conductor is made from. Different wire sizes have different ohm/foot. The longer the length of the conductor the higher the ohms/foot. Temperature also affects the resistance. Silver has the least resistance, followed by Copper, then Gold, then Aluminum. Here are some published resistances in micro ohm-cm: Silver - 1.6 Copper - 1.7 Gold - 2.2 Aluminum - 2.7
