When the diameter of a wire is doubled its resistance becomes .?
When the diameter of a wire is doubled, its cross-sectional area increases by a factor of four. Resistance is inversely proportional to cross-sectional area, so the resistance would decrease by a factor of four.
What happens to the resistance of a wire as its diameter increase?
As the diameter of a wire increases, its resistance decreases. This is because there is more cross-sectional area available for the flow of electrons, resulting in less opposition to the flow of current and thus lower resistance.
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.
Does a wire with a diameter of 0.01 mm have lower resistance than a wire with 0.1 mm?
No, the wire with a diameter of 0.01 mm will have higher resistance compared to a wire with a diameter of 0.1 mm. Resistance of a wire is inversely proportional to its cross-sectional area, so a thinner wire will have higher resistance.
How are resistance and the diameter of a wire related?
Resistance is inversely related to the diameter of a wire. A larger diameter wire will have less resistance compared to a smaller diameter wire, assuming other factors like length and material remain constant. This is because a larger diameter wire provides more space for electrons to flow through, resulting in less resistance to the flow of current.

What happens to the current of the wire when the length increases?
resistance is directly proportional to wire length and inversely proportional to wire cross-sectional area. In other words, If the wire length is doubled, the resistance is doubled too. If the wire diameter is doubled, the resistance will reduce to 1/4 of the original resistance.
How does temperature affect resistance of a wire?
If you are asking if a hot wire has a greater resistance than a cold wire then the answer I would say is yes. Cold wires have always had less resistance than hot wires

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.
Ampacity or the maximum flow of electricity for a time period increases as wire diameter increases?
Yes, that is correct. Ampacity, which is the maximum amount of electricity a wire can safely carry, increases as the wire diameter increases. This is because a thicker wire has less electrical resistance, allowing more current to flow through without overheating the wire.
What are the three factors that would give a piece of copper wire high resistance?
High resistance in a copper wire can be caused by factors like a longer wire length, a thinner wire diameter, and the material's high temperature, which increases resistance due to increased collisions among electrons.
What happens to voltage when wire length increase?
When the length of the wire increases voltage drop across the wire will occur.There are two factors that can result in voltage drop. One diameter of the wire, two length of the wire.Voltage drop increases with increase in length of wire, whereas voltage drop decreases with increase in diameter (cross section area) of the wire.G.RAOAnswerIf you are asking what happens to the voltage across a length of wire when its length increases, the answer is nothinghappens! The voltage applied to the wire is determined by the supply, not by the load (i.e. the wire).
How is a current affected across a wire if its resistance increases?
As the resistance increases the temperature will also increases....
