Resistivity will remain the same because it depends on two factors,i.e,nature of the material and temperature.

What happens to the resistance as the area increases?

Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.


What happens to the resistance of a wire as it's length increases?

Other things being equal, a greater length will result in more resistance.


What happens to insulation resistance when increasing cable length?

The insulation resistance remains the same throughout the entire length of the conductor.


Which is a better conductor between a short wire and long wire?

Double the length is double the resistance. Resistance of a wire is the resistivity of the material, times the length, divided by the cross-section area.


What is the value of the resistance when both length and diameter are double?

Doubling the diameter of a circular-section conductor will quadruple its cross-sectional area and, therefore, reduce its resistance by a quarter. Doubling the length of a conductor will double its resistance. So, in this example, the resistance of the conductor will halve.

Does resistance increase as the cross-sectional area of the wire?

the resistance can never increase or decrease....... (you can't open the resistor and take out the something and make the resistance increase or decrease)AnswerSince resistance is directly proportional to the length of a conductor, increasing the length of a wire will increase its resistance. For example, if you double its length, you will double its resistance.


What is the Change in resistance of wire when its length is double?

Assuming the wire follows Ohm's Law, the resistance of a wire is directly proportional to its length therefore doubling the length will double the resistance of the wire. However when the length of the wire is doubled, its cross-sectional area is halved. ( I'm assuming the volume of the wire remains constant and of course that the wire is a cylinder.) As resistance is inversely proportional to the cross-sectional area, halving the area leads to doubling the resistance. The combined effect of doubling the length and halving the cross-sectional area is that the original resistance of the wire has been quadrupled.


What happens to the current when the voltage is doubled and the resistance is constant?

I = E/R If resistance is constant, then current is directly proportional to voltage. Double the voltage ===> the current will also double.


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.


What happens to the resistance when length is doubled n area is quadrupled?
