On what factors does resistance depend?

The resistance of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity.

How does the shape of a wire affect resistance?

This can be attributed to the lower amount of resistance that is present in the wider pipe. In the same manner, the wider the wire, the less resistance that there will be to the flow of electric charge.

Does resistance depend on material?

Resistance depends on an object’s size, shape, and material. In Figure 3 below, the cylinder’s resistance is directly proportional to its length l. The longer the cylinder, the higher the resistance.

What are the factors on which the resistance of a conductor in the shape of a wire depends?

Answer

• Length of the conductor.
• Area and cross-section of the conductor.
• Effect of the material of the conductor.
• Effect of temperature on the material.
• Nature of the conductor.

Does resistance depend on shape and size of conductor?

It also depends on the shape and size of the conductor. The resistance of the given conductor depends on the length of the conductor and also the cross sectional area of the conductor. Resistance of a conductor is directly proportional to its length and inversely proportional to its cross sectional area.

Does thickness affect resistance?

The thickness of the wire does affect the resistance. The thinner the wire, the higher the resistance.

Does bigger wire have less resistance?

The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current.

Which factor does not affect the resistance?

The resistance of a conductor does not depend on Pressure. Conductors show less resistance and Insulators show very high resistance. So it depends on the material. It is inversely proportional to the cross-sectional area of the wire.
