Does a thicker or thinner wire have more resistance?

The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current. When resistance is increased in a circuit , for example by adding more electrical components , the current decreases as a result.

Which is better for passing current a thicker wire or thinner one?

The thin wire will conduct electricity, but there is more electrical resistance. The thicker wire is like the four lane highway. There’s a lot less electrical resistance, and as a result, that light bulb burns brighter because more electricity can reach it.

Why would someone choose a thicker wire over a thinner wire?

Electrons take longer to move through smaller wire than through larger diameter wire. The larger diameter of the bigger wire offers more area for electrons to move through the circuit. For this reason, smaller gauge wire is rated for lower amperage (electric current) limits than larger gauge wire.

What effect does the thickness of a wire have on its resistance?

The longer a wire is the more resistance it has due to the longer path the electrons have to flow along to get from one end to the other. The larger the cross sectional area, the lower the resistance since the electrons have a larger area to flow through. This will continue to apply no matter how thick the wire is.

Does a thicker wire have more resistance?

The longer the wire, the more resistance that there will be. Second, the cross-sectional area of the wires will affect the amount of resistance. Wider wires have a greater cross-sectional area. Water will flow through a wider pipe at a higher rate than it will flow through a narrow pipe.

What increases wire resistance?

Resistance of a wire increases with decreasing cross sectional area, increasing length and increasing temperature. The material it is made out of also determines what a wires resistance is.

Are thicker wires better?

A wire’s electrical resistance depends on its length and thickness. Longer wires provide greater resistance than shorter wires. Given two wires of the same length, the thicker wire would have smaller resistance than the thinner wire.

Is positive wire thicker?

Positive has to be bigger to maintain the same voltage and amperage as the line gets longer.

Can you oversize wire?

yes, as long as it fits under the breaker lugs it is fine. Many times wire is oversized due to long distance pulls resulting in increased voltage drop. The thing you cannot do is undersize the wire for the rated breaker it is under.

What are the 4 factors affecting the resistance of a conductor?

There are four factors affecting resistance which are Temperature, Length of wire, Area of the cross-section of the wire, and nature of the material.

On what factors does the resistance of a wire depend?

The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. See resistivity. The resistance of a conductor, or circuit element, generally increases with increasing temperature.

Which of the wire has low resistance?

1. Length. A short wire has a lower resistance than a long one*. Resistance is directly proportional to the length of the path through which current flows: R ∝ L.

Which wire exerts more force than the other wire?

Wire 1 exerts more force on wire 2 than wire 2 exerts on wire 1 Wire 2 exerts more force on wire 1 than wire 1 exerts on wire 2 Wire 1 exerts the same magnitude force on wire 2 as wire 2 exerts on wire 1

How do you find the force on wire 2?

To find the force on wire 2, use: F= I2L× B1 We don’t have a length to use for wire 2, but at least we can get the force per unit length: F L I2B1 μoI1I2 2π d By the right-hand rule, a current out of the page in a field up gives a force to the left.

What is the magnitude of the magnetic force on wire 2?

Using the infinite wire equation, wire 1 sets up a magnetic field that wire 2 experiences. The magnitude of this field, at wire 2’s location, is: B1 μoI1 2πd To find the force on wire 2, use: F= I2L× B1 We don’t have a length to use for wire 2, but at least we can get the force per unit length: F L I2B1 μoI1I2 2π d

What happens when you put thicker wire in a parallel circuit?

When you have a thicker wire, it effectively acts like this parallel circuit. Imagine you have a single strand of wire. It has a certain conductance and a certain resistance. Now imagine you have a wire that is composed of 20 individual strands of wire, and each strand is as thick as your previous single strand.
