Increasing wire thickness decreases its resistance, while increasing its length
increases its resistance.
Provided the voltage between the ends of the wire is constant, the current
through it is inversely proportional to its resistance.

Thicker wires have lower resistance compared to thinner wires because they have more cross-sectional area through which the current can flow. This results in less opposition to the flow of electrons and lower resistance in the thicker wire. Conversely, thinner wires have higher resistance due to their smaller cross-sectional area.

Does thickness of wire affect resistance?
Yes, the thickness of a wire affects its resistance. Thicker wires have lower resistance because they allow more current to flow through with less resistance compared to thinner wires. Thicker wires have more cross-sectional area, providing more space for the electrons to move, resulting in lower resistance.
What are factors that affect resistance of electricity?
Factors that affect resistance of electricity include the type of material the wire is made of (e.g. copper vs. aluminum), the length of the wire (longer wires have higher resistance), and the cross-sectional area of the wire (thicker wires have lower resistance). Temperature also affects resistance, with higher temperatures typically leading to higher resistance.
Why does the length of wire affect the resistance?
The length of a wire affects resistance because there is more wire for the electrons to travel through, resulting in more collisions with the wire's atoms and increased resistance. Longer wires have higher resistance compared to shorter wires of the same material and thickness due to this increased path length for electrons to travel.
What is the effect of changing the thickness of the wire?
Changing the thickness of the wire will affect its resistance. Thicker wire has lower resistance, allowing more current to flow through it with less energy loss as heat. Thinner wire has higher resistance, restricting the flow of current and causing more energy to be lost as heat.
Does the thickness of wire affects the flow of current?
Yes, the thickness of a wire, also known as its gauge, does indeed affect the flow of current. Thicker wires have lower electrical resistance, allowing more current to flow through them compared to thinner wires of the same material. Thinner wires will have higher resistance, which can create heat and reduce the amount of current flowing through them.

Does the thickness or the length of the wire effect the brightness of the bulb?
The thickness of the wire (resistance) and length of the wire can affect the brightness of the bulb. Thicker wire has less resistance, allowing more current to flow and producing a brighter bulb. Shorter wire lengths also reduce resistance, resulting in a brighter bulb due to more current flowing through it.
What does resistance depend on?
Resistance depends on the thickness and length of the wire used, as well as the conductor used. For example, a short, thick wire made of copper will conduct electricity better than a long, thin wire made of, say, iron.AnswerResistance is directly proportional to the length and inversely proportional to the cross-sectional area (not 'thickness') of a material. Its constant of proportionality is called resistivity which is affected by temperature -so temperature indirectly affects resistance.
Would not reduce resistance in a copper wire?
Resistance will only be reduced by changing the thickness of the wire or the wire's temperature. It's apparent impedance can be changed by placing it in an electric field as well.
How does the thickness of wire affect the resistance?
Thicker wire has less resistance than thinner wire due to lower electrical resistance. Thicker wire allows more electrons to flow through it easily, resulting in less opposition to the flow of electric current.
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.
