If both the diameter of wire and its length were quadrupled what will happen to its resistance?
If both the diameter and length of a wire are quadrupled, the resistance of the wire will increase by a factor of 16. This is because resistance is directly proportional to the length of the wire and inversely proportional to the cross-sectional area of the wire, which is determined by the diameter. By quadrupling both, the resistance will increase by 4^2 = 16 times.
What happens to the current in a wire as its diameter decreases?
As the diameter of a wire decreases, the current-carrying capacity also decreases due to increased resistance. This can lead to overheating of the wire and potential failure if the current exceeds the wire's new lower capacity. It is important to properly size wires to handle the intended current to prevent safety hazards.
What would happen to the strength of the field if the current was increased?
If the current in a wire is increased, the strength of the magnetic field around the wire would also increase. This is because magnetic field strength is directly proportional to the amount of current flowing through the wire.
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 is the diameter of 16 gauge wire?
16-gauge wire has a diameter of 0.05082 inches.

What is the cable diameter of a twin copper wire?
There isn't a specific diameter. The thicker the wire the more current it can convey. This diameter will be part of your calculations for your circuit.
Which wire would have the least resitance a large diameter or small diameter wire and why?
large diameter wire simply because it will move easier Technically they would have the same resistance, but the larger diameter wire would allow more current to flow as it would have more room to move.
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.
If the wire dia is 4mm then what is the gauge?
A wire with a diameter of 4mm corresponds to a wire gauge of approximately 6 AWG (American Wire Gauge). The relationship between wire diameter and gauge is not linear, so different wire diameters can correspond to the same gauge.
What is the diameter of 18 awg wire?
The diameter of an 18 AWG wire is approximately 1.02 millimeters or 0.0403 inches.
Which awg wire gauge indicates the smallest wire diameter?
The larger the wire gauge, the smaller the diameter. 12 gauge is bigger than 14 gauge.
