What are the factors on which the heat produced the electric current depends upon?
It depends on1 the resistance of wire.2the voltage between the ends of the wire.3the flowing current time.
What happens to the current of the wire when the length increases?
resistance is directly proportional to wire length and inversely proportional to wire cross-sectional area. In other words, If the wire length is doubled, the resistance is doubled too. If the wire diameter is doubled, the resistance will reduce to 1/4 of the original resistance.
Which wire has the lowest resistance?
Resistance is directly-proportional to the length and resistivity of a conductor, and inversely-proportional to its cross-sectional area. So a shorter wire would have less resistance than a longer wire made from the same material, and a wire with a greater cross-sectional area would have less resistance than one with a smaller cross-sectional area made from the same material. Resistivity depends on the material from which the wire is made, with some materials being better conductors than others. For example, silver has the lowest resistance compared with other metal conductors having identical dimensions. Similarly, a copper wire will have a lower resistance than an aluminium wire of identical dimensions.
What is the required wire size for a 230 feet run 480 volt 100 amp?
Depends on length. The more length, the more resistance.
What is the formula for calculation of wire resistance?
R = resistance = rho * L / S rho is resisitivity in [Ohm m], it depends on the material (Copper: 2e-8 [Ohm m]) L is wire length [m] S is wire cross section [m] EDIT: for high frequencies, you may also wanto to take sink effect into account (~MHz)
Electrical resistance in a wire depends on the wire's?
It's dependent on the wire's composition. That is, what material it is made of. <<>> The electrical resistance in a wire depends on the wire's length and cross sectional area.
What is the resistance of metal wire?
the resistance is depends on the type of the metal and ith length
What is a fundamental property of a wire that depends on a wire's moleculal structure and size?
Resistance
If you cut a wire what happend to resistance?
If you are talking about the total resistance in a circuit , it depends on the components in the circuit and the location of the cut.If you are talking about a single wire, the resistance becomes infinite (or close to it) when the wire is cut.
Will a short thick metal wire have better resistance compared to a long narrow metal wire?
"Better" depends on how much resistance you need for your circuit design.A short thick wire will have less resistance than a long thin wire of the same substance.Whether that's better or worse depends on how you plan to use the wire.
What happens to resistance of the wire if the wire is short?
Short wire has less resistance Long wire has more resistance Thick wire has less resistance Thin wire has more resistance
What is the resistance of a 6 000 foot piece of 1 0 copper wire?
The answer depends on the cross sectional area of the wire. This is not given.
The magnitude of the resistance of a wire depends on?
Temperature, Length of wire, Area of the cross-section of wire and nature of the material.
What are the factors on which the heat produced the electric current depends upon?
It depends on1 the resistance of wire.2the voltage between the ends of the wire.3the flowing current time.
How does the thickness of the wire affect resistance?
A thicker wire has less resistance than a thinner wire.
How does the thickness of wire affect the resistance?
A thicker wire has less resistance than a thinner wire.
What are the two factors of a wire that will alter its resistance?
The resistance of the wire is directly proportional to the length and inversely proportional to the area of cross section. Also it depends on the material of the wire with which it is made. So three factors. Length, area of cross section, material.
