What happens to the resistance of a wire if the diameter is doubled?

The resistance of the wire becomes one-fourth, when the diameter of the wire is doubled.

What happens to the resistance of a conductor if its length is increased three times?

ANSWER ➡ Resistance is also changed by 3 times . We know that , Resistance is directly proportional to the length of the conductor .

How does the resistance of a wire change when its diameter is tripled?

Resistance becomes 3 times.

What happens to the resistance of a conductor if its diameter increases?

The longer the cylinder, the higher the resistance. Additionally, the resistance is inversely proportional to the cross sectional area A. If the diameter of the cylinder is doubled, the cross-sectional area increases by a factor of 4. Therefore, resistance decreases by a factor of 4.

What is the effect on the current flow with increased diameter of conductor?

Explanation: Increased diameter of conductor allows high current flow.

Does the resistance of a copper wire increase or decrease when both the length and diameter of the wire are doubled explain?

Answer: Originally Answered: If radius of a wire is doubled then what happens to its resistance? So by doubling the radius of wire , the resistance of the wire will become 1/4 time the previous resistance.

What happens to the resistance of a conductor if the length of wire is increased three times keeping the radius same?

The resistance of a wire is inversely proportional to its area and directly proportional to its length. When the length is tripled then resistance will also become three times.

How will the resistance of a wire change 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.

How does the resistance of a wire vary with its diameter?

By increasing the area of cross section, the resistance will decrease. By increasing the diameter, the resistance will decrease.

What is the relationship between diameter and current?

The channel diameter (D), defined as the width of the intensity profile at 10\% level, increases with the increasing peak current (Ip) up to 3 kA. The relationship between the two parameters can be represented by the equation, D = 8.36 ln(Ip) + 1.598, where D is in mm and Ip is in kA.

What factors affect the amount of resistance of a conductor?

There are four factors which influence the amount of resistance of a conductor: type of material, length, thickness and temperature. Different materials will offer different amounts of resistance. Longer length resistors will offer more resistance than shorter resistors.

What is the change in resistivity when length of wire increases?

Resistivity is depending on material of wire, and as material of wire is not changing resistivity will not change. Their is no mention about change in length of wire, so Length of wire is same. Resistance Becomes 1/4th , if DIAMETER OR RADIUS is DOUBLED. (The reason is given below)

What is the resistance of the wire when diameter is doubled?

Now if the diameter is doubled then the new resistance is R’=4ρL∕(π(2d)²) =4ρL∕(4πd²) =0.25R. Hence we see that the resistance of the wire becomes 25\% of original resistance. This result is showing that the resistance decreases as we increase the cross-section area keeping the length constant.

How do you calculate the resistance of a stretched wire?

The change in resistance can be easily calculated by applying the following formula: Resistance = (Specific Resistivity Constant x Length of wire) / Area of cross section of wire When the wire is stretched to 3 times its original length, its cross section is also reduced to one third of what it was before.
