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)
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.
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
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.
Does the resistance of a wire depend on the cross section area of the wire?
No, the resistance of a wire primarily depends on its length, resistivity, and temperature. The cross-sectional area of the wire influences the wire's resistance indirectly by affecting the wire's overall resistance. A larger cross-sectional area generally results in lower resistance due to increased conducting area for current flow.
Does a short copper wire have more resistance then a long one?
No, resistance depends on the material, cross-sectional area, and temperature of the wire. A shorter wire will have less resistance compared to a longer wire since it offers less opposition to the flow of electrical current.
What is the resistance value of 1 meter copper wire?
The resistance value of a 1 meter copper wire depends on its gauge (thickness) and temperature. For example, a 1 meter wire of 24-gauge copper has a resistance of about 25.67 ohms at room temperature. It is important to consider these factors when calculating the resistance of copper wire.
What does the resistance of the wire depend on?
The resistance of a wire depends on three main factors: its length, its cross-sectional area, and the material it is made of. Generally, longer wires have higher resistance while thicker wires have lower resistance. The material's resistivity also plays a significant role in determining the wire's resistance.
If you cut a wire what happend to resistance?
Cutting a wire will increase the resistance in the circuit because now the current cannot flow through the cut wire path, creating an open circuit. This results in higher resistance and lower current flow in the circuit.
What are the two factors of a wire that will alter its resistance?
The two factors that will alter a wire's resistance are its length and cross-sectional area. Increasing the length of the wire will increase its resistance, while increasing the cross-sectional area will decrease its 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.
