Which one of the following does not affect the electrical resistance of a body?
the second one has no affect.
How does electric resistance affect electric charges?
In an electrical circuit ,, resistance is the force that resists the flow of electricity thru the circuit .. this is used in light bulbs to create the heat and light that we expect from the bulb .. and heat in a toaster fron the resistance in a wire making it hoy enough to cook the surface of the bread
How does an object length affect its electrical resistance?
Assuming constant cross section, the resistance is directly proportional to the length.
Definition for electrical energy?
Energy associated with the presence or movement of electric charges
Does thickness of a metal affect its electrical resistance?
Metals are conductive, but are not perfect conductors and so they have some electrical resistance. How the resistance of the metal is affected by "thickness" depends on what you mean by thickness. If the electrical current has to flow through a longer piece of metal, then the resistance of the metal to electrical flow would be greater. However, if you take that same length of metal and increase the area of the metal by increasing its "thickness", then the resistance of the metal becomes less.
Why is electrical resistivity important to a design engineer?
electrical resistance increases current flow decreases.so to know the current flow in the network ,electrical resistance is required.AnswerResistivity is important, because it is one of the three factors that affect the resistance of a material. The other factors are the length and cross-sectional area of the material.
How does spinning affect the air resistance of lime seeds?
spinning changes the direction of movement in air,thus affects the air resistance
Factors affecting movement?
Three factors that affect movement are friction, wind resistance, and velocity. Friction is the resistance that a single object encounters when moving over another object. Velocity is speed, and wind resistance is the opposing force on an object.
How does air resistance affect us in everyday life?
It is all around us and affects in everyday life with every movement. Air resistance acts against us.
What are the four factorws affecting electrical resistance?
There are really only three things that affect electrical resistance. They are the length and cross-sectional area of a conductor and its resistivity. However, resistivity depends not only on the material from which the conductor is manufactured, but upon its temperature. So you could say that temperature indirectly affects resistance via its resistivity.
In electrical installation why do you need to ensure the cables are not twisted or plaited?
Because it would affect the Cross sectional area of the conductor therefore altering the resistance.
Does the length of a conductor not affect its resistance?
The length of a conductor Does affect it's resistance.The longer it is, the more the resistance.
