What are factors that affect resistance of electricity?
Temperature, thickness, length and type of wire.
Do different types of materials affect air resistance differently?
Yes, different types of materials can affect air resistance differently. Smooth surfaces such as glass or metal tend to have lower air resistance due to their ability to create laminar flow. Rough surfaces like fabrics or textured objects tend to create more turbulence, increasing air resistance. Additionally, the shape and surface area of an object also influence air resistance.
What factors affect the resistance of material to the flow of energy?
The resistivity of metals increases with temperature. Going the other way, some metals become superconductors if the temperature is lowered to a sufficiently low temperature.
Does the air resistance has an affect on the projectile or not?
Not "affect"; the word is "effect" in this case. Yes, air resistance has an effect on projectiles.
What three variables affect peripheral resistance to blood flow?
Resistance is determined by three properties: the lengthand cross-sectional area of a material, and its resistivity. Since resistivity is affected by temperature, you could say that temperature indirectly affects resistance.
How might ambient temperature may affect the resistance values you would measure in a circuit?
Ambient temperature might affect the readings of the resistance value you would measure because the resistance of some materials changes with the temperature.
What factor affects the resistance of a conductor?
This are the factor which affect resistance of a conductor (1). Area of conductor (2). Length of conductor (3) Temperature (4). Type or substance of material used in conducting the electricity.
Does the temperature of the liquid affect how materials dissolve in it?
Yes, the higher the temperature, the faster materials dissolve in the given liquid
Do the resistance depend on temperature and bias voltage?
Yes it depends on temperature and bias voltageAnswerNo. Although temperature may affect resistance indirectly (if actually affects resistivity, rather than resistance), a material will have resistance whether there is a voltage present or not.
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.
How does temperature affect resistance of a wire?
If you are asking if a hot wire has a greater resistance than a cold wire then the answer I would say is yes. Cold wires have always had less resistance than hot wires
What are factors that affect resistance of electricity?
Temperature, thickness, length and type of wire.
Reducing voltage in a circuit does not affect resistance?
Reducing voltage in a circuit does not directly affect resistance. It affects current. Resistance is an independent variable.Ohm's law: voltage equals current times resistance.However, reducing voltage and/or current does reduce power, which reduces temperature, which can change resistance because resistance is usually affected to some degree by temperature.
How does tempreture affect resistance?
Temperature has a positive relation on resistance. This is because as the temperature gets higher, the molecules in the surface move more, which will cause more resistance since the molecules will be moving and bumping into things.
How does the temperature affect the resistance of various resistors?
resistance depends on temperature too.. we know that R=R0( 1 + rho (change in temperature) ) where R= present resistance R0=resisance at 00C rho= resistivity of a material now if the change of temperature is positive , means if the temerature increases then the resistance will also increase and vice versa
If the current increases what happens to resistance?
An increase in current will only affect resistance if it causes the temperature of the conductor to change. For pure metallic conductors, and increase in temperature will cause an increase in resistance.
What does power divided by speed equal?
Ohm so correctly said: Voltage divided by current equals resistance. Voltage divided by current will tell you the value of a circuit's resistance. But resistance is not affected by either voltage or current. It is determined by the length, cross-sectional area, and resistivity (type of conducting material) of the conductor. Resistivity is, in turn, affected by temperature. So voltage divided by current tells you what the resistance happens to be - changes in voltage or current do not affect resistance.
