Does specific resistance depend on length?

The resistance of a conductor depends mainly on three things; The LENGTH of the conductor. The CROSS SECTIONAL AREA of the conductor. The MATERIAL of which the conductor is made.

Does specific resistance depend on mass?

The specific resistance or resistivity of a wire is the property of the material of it. It does not depend on mass, length or cross-section of wire.

How does a resistance and B specific resistance of a wire depend on its I length and II radius?

Resistance is directly proportional to the length and inversely proportional to the square of radius. Specific resistance is independent on the dimensions of a wire.

How does specific resistance of a wire depends on its length and radius?

We know that the resistance of a wire is inversely proportional to the cross-sectional area of the wire. This means that the resistance of the wire and radius of the wire is inversely proportional to each other. Therefore, as the radius increases, the resistance of wire decreases.

On which of the given resistance does not depend *?

It depends only on the material of the conductor. It does not depend on the shape and size of the conductor. Whereas the resistance does depend on the shape and size of the conductor.

How does resistance and specific resistance depends on length and radius?

How does the resistance of a wire depends on its area of cross section?

Resistance is inversely proportional to area of cross section. larger will be the area lower will be the resistance and vice versa. this is because through a conductor with large area of cross section current can easily flow and hence resistance is low.

How does the resistance of a metallic wire depend upon its temperature?

With the increase in the temperature of a conductor, both the random motion of electrons and the amplitude of vibration of fixed positive ions increase. As a result, the number of collisions increases. Hence, the resistance of a conductor increases with the increase in its temperature.

On which of the given resistance does not depend on density?

No, resistance does not depend on the density of the material. However, it depends inversely on the density of free electrons in the material. Stay tuned with BYJU’S to learn more about other concepts such as formula of resistance.

Does resistance depend on nature of material?

Yes the resistance of a conductor is dependent on the nature of the material. The formula for determining the resistance of a conductor is R = ρL/A where R is the resistance in ohms ρ is the resistivity of the material in ,Ωm; L is the length of the material and A is the cross-sectional area in m^2.

How does a resistance and B specific resistance of a wire depend on its 1 length and II radius?

How does specific resistance depend on radius?

This means that the resistance of the wire and radius of the wire is inversely proportional to each other. Therefore, as the radius increases, the resistance of wire decreases. So, the resistance of a wire depends on its radius. Stay tuned with BYJU’S to learn more about other concepts such as Ohm’s law and resistance.
