The resistance of a wire increases as its length increases. This is because as the length of the wire increases, there are more atoms for the electrons to collide with as they pass through the wire, leading to more opposition to the flow of electric current and a higher resistance.

A lenght of cirular wire as a resistance of 1 ohms if its the diameter was double its resistance woul be.?
If the diameter of the circular wire is doubled, the resistance will decrease by a factor of four, resulting in a resistance of 0.25 ohms. Resistance is inversely proportional to the cross-sectional area of the wire, which is affected by the diameter.
How does the resistance of a wire vary with its length?
The resistance of a wire is directly proportional to its length. This means that as the length of the wire increases, the resistance also increases. This relationship is described by the formula R = ρ * (L/A), where R is resistance, ρ is the resistivity of the material, L is the length of the wire, and A is its cross-sectional area.
What are the dependent variables in a copper wire resistance experiment?
The dependent variables in a copper wire resistance experiment would typically be the resistance of the copper wire being measured. This would vary based on factors like the length and thickness of the wire, as well as the temperature.
What happens to resistance of the wire if the wire is short?
If the wire is short, its resistance will likely decrease. A shorter wire has less length for electrons to travel through, resulting in lower resistance according to the formula R = ρL/A, where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
What will you need to measure to find out which wire has the greatest resistance?
To find out which wire has the greatest resistance, you will need to measure the resistance of each wire using a multimeter. Connect the multimeter to each wire separately and record the resistance values displayed. The wire with the highest resistance value will have the greatest resistance.

How would you find out the length of the wire effects the voltage drop across the wire when the current passing is kept constant?
A: There are tables that qualify IR drops for wire lenght. All wire do offer resistance to current this current will cause directly a volatge drop according to the wire resistance so it can be measured to find the IR drop

How does length affect resistance of a wire?
In general, the longer the wire, the greater the resistance. This is because a longer wire offers more resistance to the flow of electrons compared to a shorter wire. The resistance of a wire is directly proportional to its length.
Which has greater resistance a thick wire or a thin wire of the same lenght?
The thin wire has more resistance to the flow of electric current than the thick wire. If you connect the wires to a battery the battery will supply electrical pressure (voltage) and the wires serve similar to pipes that conduct water under pressure. A small pipe exhibits more resistance to the flow of water and a thin wire exhibits more resistance to the flow of electrons. However, as you point out different wire materials exhibit different resistances for equal sizes (silver conducts better than copper, etc.).
How does the thickness of the wire affect resistance?
A thicker wire has less resistance than a thinner wire.
A 4 ohm resistance wire is doubled on it calculate the new resistance of the wire?
The resistance of a wire is directly proportional to its length, so doubling the length will also double the resistance. Therefore, doubling the 4 ohm resistance wire will result in a new resistance of 8 ohms.
What is the resistance of a connecting wire?
The resistance of a connecting wire can vary depending on its material, length, and thickness. In general, wires with a higher resistance will impede the flow of electrical current more than wires with lower resistance. It is important to consider the resistance of connecting wires in electrical circuits to ensure proper functionality.
How does the resistance of a wire vary with its diameter?
The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Therefore, as the diameter of a wire increases, its cross-sectional area also increases, leading to a decrease in resistance. This relationship follows the formula for resistance: R = ρL/A, where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
