What are the factors affecting resistance of material?

Resistance is the property of the material that restricts the flow of electrons. There are four factors affecting resistance which are Temperature, Length of wire, Area of the cross-section of the wire, and nature of the material.

What are the factors affecting resistance of a wire class 10?

The resistance of the conductor depends on the following factors:

• The temperature of the conductor.
• The cross-sectional area of the conductor.
• Length of the conductor.
• Nature of the material of the conductor.

What four things does the resistance of a wire depend on?

resistance is the property of that wire to oppose current flow. It depends on its physical dimensions such as length,area of cross section ,material properties( resistivity), atmospheric conditions in which it is used such as temperature, pressure etc…

Which of these factors does not affect the resistance of a wire?

Answer on Question #45708, Physics, Electromagnetism The only item not listed here is voltage. Voltage value is not affect resistance (if we will not take into account any temperature changes).

Which of the following factor can not affect resistance of a wire?

EXPLANATION: The resistance of a conductor does not depend on Pressure. So option 1 is correct.

What determines resistance in a wire?

To calculate the resistance R of a wire, we need to know three things: its length – the longer the wire, the greater its resistance. its cross-sectional area A – the greater the area, the less its resistance. the resistivity of the material r – the greater the resistivity, the greater its resistance.

Which factor does not affect the resistance of a material?

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.

What are the factors that affect resistivity?

Factors Effecting the Resistivity of Electrical Materials

• Temperature.
• Alloying.
• Mechanical stressing.
• Age Hardening.
• Cold Working.

Which factor is least likely to affect the resistance of a conductor?

Which factor is least likely to affect the resistance of a conductor? the overall shape of the conductor.

What are the main factors that affect the resistance in a conductor?

The main factors that affect the resistance in a conductor are: · Length · Temperature · Cross sectional area · Material · Magnetism The factor that we are going to change is the cross sectional area. Hypothesis: I think that the higher the cross sectional area, the lower the resistance in the conductor will be.

What is resistance of electrical circuit?

Factors Affecting Resistance: The word Resistance is an important term in electrical terminology. It means opposition to electric current. An electrical circuit has resistance to control to flow of current. It is dependent on certain factors. Let us see what factors affect the resistance in this article.

What is the relationship between resistance and cross sectional area?

This extra time is equivalent to the resistance met by the moving charges. Resistance is inversely proportional to the cross-sectional area of the conductor. In simple words, the thicker the conductor, the smaller is its resistance. It means that resistance is high in a thin conductor.

How does heat affect ohm’s law?

Heat is due to the motion of atoms in a material. The higher the temperature, the more is this movement. Therefore, with high temperature, resistance increases as the electrons collide more with the atoms surrounding them. Therefore, Ohm’s law is applicable with a clause that the temperature is constant.
