How will the resistance of a wire change if the diameter is doubled its length remaining the same?
From this relation we can conclude that resistance is inversely proportional to area A of the conductor. Area of the conductor becomes 4 times the area of the conductor without doubling the diameter. Thus, we can say that new resistance will decrease four times.
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.
How does resistance change when the length of wire is doubled?
So, the new resistance, after doubling the length of the wire, becomes twice of the original resistance. Hence, if the length of a wire is doubled, then its resistance becomes doubled.
How will the resistance of a wire changes if its diameter?
then resistance of wire will decrease because of diameter its area of cross section will increase. and resistance is inversely proportional to the area of cross section .
How much does the resistance of a wire changes if its diameter?
So the wire resistance is inversely proportional to diameter or cross sectional area. this means when the diameter of the wire is doubled, the resistance will be 1/4 of the original value due to R is inversely proportional to π(d/2)².
What happens to the resistance when length of conductor is doubled without affecting the thickness of conductor?
What happens to the resistance when length of conductor is doubled without affecting the thickness of conductor? … Resistance of the conductor is doubled because it is directly proportional to the length.
How does the resistance of a wire change when?
The resistance of a wire is directly proportional to its length and inversely proportional to its area (or square of inverse of diameter).
When the length of the wire is doubled its resistance also gets doubled reason the resistance of a wire is directly proportional to its length?
Therefore, when the length of the wire is doubled, resistance of the object is also doubled. Therefore, option (D) is the correct answer. Therefore, resistance is directly proportional to length of object and inversely proportional to cross-sectional area.
What happens to resistance when length is doubled without affecting?
Conclusion : In directly proportional values, when length will be doubled then Resistance will also double but when area will double the resistance will be reduced to half.
What will happen to resistance if the length of the conductor is increased?
This is how the resistance of a conductor changes, depending on the conductor’s length. Increased conductor length equals increased resistance in direct proportion. The thinner or smaller the diameter (cross sectional area), the greater the resistance.
What would be the new resistance if length of conductor is doubled and thickness is half?
hence , the new resistance comes out to be = 4 times of original resistance .
What happens when resistance is doubled?
if resistance is doubled then the current would be halved as resistance is inversely proportional to the current flowing in a circuit. that is if the resistance is doubled the current would be halved.
What happens to resistance if area is doubled?
What happens to resistance of a conductor if area of cross section is doubled? The resistance of a conductor is inversely proportional to its area of cross section. i.e., Resistance will be reduced to half.
How is resistance affected if length of a conductor is tripled and thickness is made one third?
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. If The wire is stretched 3 times the original length, the cross-section of the wire is cut to 1/3rd it’s the original cross-section.
How does the resistivity of a conductor change if its length becomes double and cross sectional area becomes half?
Answer: the resistance of a conductor is directly proportional to its length. so if length is increased then resistivity increases ande vice versa. so if length is doubled resistance will also get doubled i.e resistance is 4 times that of original resistance.
What will happen to the resistance of a conductor if its length is doubled and area of cross-section is halved?
Thus, the above equation shows that the length of the conductor and the cross-section of the conductor are doubled, then the resistance of the conductor will remain the same, there is no change in the resistance of the conductor. Hence, the option (A) is the correct answer.
How does the resistance of wire change if its diameter is tripled?
Answer: As the resistance of a wire is inversely proportional to the square of the diameter of a conducting wire if its diameter is tripled its resistance becomes 9th part of the previous resistance.
How does the resistance of wire change when diameter is tripled?
Resistance becomes 3 times.
How will the resistance and resistivity of a conductor change when its length is tripled by stretching it?
Resistivity of a conductor such as wire will increase by nine times when it is stretched by three times. It is directly proportional to the length and inversely proportional to diameter. … So the resistivity will also triple.
How does resistance of a resistor changes on changing its length and thickness?
Resistance is inversely proportional to area. As the area increases with thicker wire, the circuit resistance decreases.
How does the resistance of wire change when its material is changed to one whose resistivity is three times?
c) it’s material is changed to one whose resistivity is three times thats it the resistance will decrease nine times of initial.
How does the resistance and resistivity change if area is change?
Resistance is proportional to resistivity and length, and inversely proportional to cross sectional area.
