Is a wire thick with low electric resistance?
A wire that is thicker than another wire of the same material has less resistance
How does surface and material affect friction?
Surface and material affect friction by changing the amount of contact between objects and the roughness of the surfaces. Smoother surfaces with less friction will have less resistance to motion, while rougher surfaces with higher friction will have more resistance. The type of material can also impact friction, as some materials have a higher coefficient of friction and will create more resistance when in contact.
What happens to the resistance of a filament if it is replaced by a shorter wire?
If a filament is replaced by a shorter wire, the resistance will decrease. Resistance is directly proportional to the length of the wire, so a shorter wire will have lower resistance. This is because there is less material for the electrons to travel through, resulting in less opposition to their flow.
Which factor does not affect the resistance of a material?
The factor that does not affect the resistance of a material is the color of the material. Resistance is primarily determined by factors such as the material's dimensions, temperature, and composition.
Does aluminum have lower resistance than copper?
No, aluminum has a higher resistance than copper.
Does voltage basically measure how well a charge can flow through a less conductive material?
Voltage is electrical pressure, energy per charge, specifically joules per coulomb. The less conductive material represents more resistance. Resistance is the (in)ability to allow current flow, coulombs per second, or amperes. Since Ohm's law states that voltage is current times resistance, or resistance is voltage divided by current, we can say that resistance is joules per coulomb divided by coulombs per second, which in reduced terms is joules-seconds per coulomb squared. Its a matter of perspective, whether one considers voltage or resistance to be the "measure" of how well a charge can flow thorugh a less conductive material, but, to answer your question, yes, voltage measures how well a charge can flow through a less conductive material, because, in order to maintain constant current flow while increasing resistance, you have to increase voltage.
What happens to the resistance of a filament if it is replaced by a thicker wire?
If a filament is replaced by a thicker wire, the resistance of the circuit will decrease. Thicker wires have lower resistance because they offer less resistance to the flow of electric current compared to thinner wires of the same material and length.
How does the material of wire affect the resistance?
Basic: The larger the diameter the less resistance.Deep:R = p (L / A)The resistance is proportional to the length of the wire divided by its cross-sectional area. p is the resistivity of the material in question and varies greatly. Since area (assuming a circular wire) is A = pi * r2 the larger the diameter of the wire the lower its resistance will be.AnswerResistance is inversely proportional to the square of the diameter. So, if you double the diameter, you will quarter the resistance. If you halve the diameter, you will quadruple the resistance.
What is PFA material?
Corrosion Resistance
Which material has a greater resistance aluminum or copper wire?
Copper wire has greater resistance than aluminum wire. This is because copper is a better conductor of electricity than aluminum. This means that copper wire will have less resistance and will be able to carry more current with less energy loss.
What is the relationship between resistance and temperature in a material?
The relationship between resistance and temperature in a material is that as the temperature of the material increases, the resistance also increases. This is because higher temperatures cause the atoms in the material to vibrate more, which disrupts the flow of electrons and increases resistance.
Is electrical resistance and electrical resistivity the same?
No, they are not the same. Electrical resistance is a measure of how much a material opposes the flow of electric current, while resistivity is a property of the material itself that determines its resistance. Resistivity is an intrinsic property of the material, while resistance depends on the dimensions and shape of the material.
