# How does the resistance of a conductor depend on temperature of the conductor? Due to increase in temperature, the thermal velocities of free electrons also increases. Therefore, the number of collisions between free electrons and atoms increases. This increases the opposition to the movement of electrons and hence the resistance of the conductor.

How does resistance change with temperature? If the temperature of a metal conductor increases, the ions of the metal vibrate more vigorously. This increases the number of collisions between the free electrons and the ions. Hence, for a metal, resistance increases with increasing temperature.

Is resistance of a conductor depends on nature of the conductor?

The resistance of a conductor does not depend on the nature of material of the conductor.

How does the resistance of a conductor depend on 1 i temperature of the conductor?

Resistance is directly proportional to the temperature of the conductor. If the temperature is increased, the resistance is additionally increased.

How does the resistance of a conductor depend on the temperature of the conductor?

Since the resistance of some conductor, such as a piece of wire, depends on collisions within the wire itself, the resistance depends on temperature. With increasing temperature, the resistance of the wire increases as collisions within the wire increase and "slow" the flow of current.

How does temperature affect the resistivity of a conductor?

Resistivity is indirectly proportional to the temperature. In other words, as you increase the temperature of materials, their resistivities will decrease.

What is the effect of temperature on conductors?

Temperature Effect on Conductors, Semiconductors & Insulators –The resistance of the conductor increase with an increase of temperature. Whereas, the resistance of semiconductors and insulators decreases with an increase in temperature.

How does the resistance of a conductor depend on temperature of the conductor?

c) Temperature: Resistance is directly proportional to the temperature of the conductor. If the temperature is increased, the resistance is additionally increased.

What happens to a conductor when temperature is increased?

With increase in temperature of conductor, the number of collisions between the free electrons increases due to increase in thermal energy resulting in the random motion of electrons. These electrons find it difficult to drift in a particular direction for conduction.

How does resistance change with temperature class 10?

As there is an increase in the temperature of materials, their resistivities will decrease.

### Why is resistance directly proportional to temperature?

Resistance of a conductor is directly proportional to temperature. Reason : With the increase in temperature, vibrational motion of the atoms of conductor increases. Due to increase in vibration, probability of collision between atoms and electrons increases.

### What does resistance of a conductor depends on?

The resistance of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity. It is important to note that electrical conductivity and resistivity are inversely proportional, meaning that the more conductive something is the less resistive it is.

### Does resistance depend on nature of material?

Solution : a If we take two similar wires of same length and same diameter one of copper metal and other of nichrome alloy we will find that the resistance of nichrome wire is about 60 times more than that of the copper wire. This shows that the resistance depends on the nature of material of the conductor.

### On what factors resistance of a conductor depends Class 10?

The resistance of a conductor depends upon the resistivity, length and cross-sectional area of the conductor which is given by the relation (R=ρAl). It does also depend on other physical factors like temperature etc. Its SI unit is Ohm (Ω).

### How does the resistance of a conductor depend on 1 i temperature of the conductor II area of cross-section of the conductor?

Answer: resistance is directly proportional to the length of the wire and inversely proportional to the area of cross section of the wire. if the temperature increases, the resistivity increases.

### How does resistivity of a conductor depend on temperature?

The resistance of a conductor increases with an increase in temperature because the thermal velocity of the free electrons increases as the temperature increases.

### What happens to the resistance of a conductor when its temperature is increased?

With increasing temperature, the resistance of the wire increases as collisions within the wire increase and "slow" the flow of current. The amount of change is determined by the temperature coefficient.

### Why does resistivity decrease with temperature?

The resistivity of a semiconductor decreases with temperature. This is because of increasing temperature, the electrons in the valence band gain sufficient thermal energies to jump to the conduction band. As the number of electrons in the conduction band increases, so conductivity increases and resistivity decreases.

### How does resistance and resistivity vary with temperature?

Explanation:Resistance and resistivity vary with temperature means -when we increase the temperature,the random motion of electron increases.As a result the number of collision increases . Hence ,the resistance of conductor and resistivity increases with the increase in temperature.

### What is the effect of temperature on resistance for conductors?

Well, to answer this question directly we can say that resistance is directly proportional to temperature. The resistance will increase if we raise the temperature of let's say a metallic conductor.

### How does temperature affect resistance in a conductor?

Heating the metal conductor causes atoms to vibrate more, which in turn makes it more difficult for the electrons to flow, increasing resistance.

### What happens to a resistance of a conductor when the temperature is increased?

With increasing temperature, the resistance of the wire increases as collisions within the wire increase and "slow" the flow of current. The amount of change is determined by the temperature coefficient.

### When temperature increases resistance of a conductor?

The resistance of a conductor increases with an increase in temperature because the thermal velocity of the free electrons increases as the temperature increases. This results in an increase in the number of collisions between the free electrons.

### How does temperature affect the resistance?

As temperature increases, the resistivity of metal increases, giving it a positive temperature coefficient of resistance.

### How are resistance and temperature proportional to each other?

Temperature: It is directly proportional to resistance. As the temperature increases, the value of resistivity increases so resistance increases.
