What happens to the resistance when the length of the wire is halved?

The answer :If the length of the wire is halved, it’s resistance also gets halved. Reason: Resistance is directly proportional to length of the conductor . Hope it was helpful.

What happens to the resistance of a wire which is cut to half of its original length?

Resistance is proportional to the length. If you cut a piece of wire lengthwise into two identical pieces of the same length as the original piece, but each with half the cross-section as the original piece, then the resistance of each piece will be double the resistance of the original piece.

How does resistance of a wire be changed if it is cut into his identical pieces?

Resistivity is material property. It will not change by cutting the wire.

When length of conductor is halved then its conductivity becomes?

Thus, whatever be the length of the conductor, the conductivity for the given material will remain the same. So, if the length of a conductor is halved, its conductivity will be unchanged.

What happens to area when length is halved?

Area become one-fourth when side of square is halved.

What will happen to the resistance of the wire when its length become half and area becomes twice?

As the length of wire gets doubled, the cross-sectional area will become half of its previous value because volume of wire remains constant. Hence, we can see that the new resistance is four times the previous resistance.

What would be the new resistance if length of conductor is doubled and thickness is halved?

hence , the new resistance comes out to be = 4 times of original resistance .

What happens to the resistance and resistivity of a wire if the wire is cut into two equal halves?

The resistivity of the material will not change (remain the same) as it is independent of the length or cross-section of the wire. The resistance will change but resistivity will remain the same.

What change is represented by cutting of copper wire into 4 pieces?

1) when it is cut into four equal part, the length of one-fourth of the original length. 2) when the pieces are connected in parallel, Thus equivalent resistance of the parallel combination of the cut part is equal to the one sixteenth of the original resistance.

How does the resistance of a wire vary inversely?

Resistance of a wire varies inversely as the area of cross section of the wire i.e., Resistance of a wire is directly proportional to its length, i.e., R ∝ l and varies inversely as the area of cross section of the wire i.e., R ∝ 1 / a or R ∝ 1 / πr 2

What is the relation between resistance and conductance?

Conductance formula and resistance formula 1 R is the resistance in Ω, 2 ρ is the resistivity of material in Ω * m, 3 L is the length of wire, 4 A is the cross-sectional area of the wire.

What happens when you double the length of a wire?

When the wire is doubled on itself, its length becomes halved (L/2) and area of cross-section becomes doubled (2 A). A hot plate of an electric oven connected to a 220 V line has two resistance coils A and B, each of 24 Ω resistance, which may be used separately, in series, or in parallel.

What is the wire resistance formula used in the calculator?

Our wire resistance calculator uses the following resistance formula: R = ρ * L / A
