The three main factors that affect the resistance in a wire are the material of the wire (different materials have different resistivities), the length of the wire (longer wires have higher resistance), and the cross-sectional area of the wire (thicker wires have lower resistance).

What three factors affect the resistance in a circuit?
The three main factors that affect resistance in a circuit are the material the wire is made of, the length of the wire, and the cross-sectional area of the wire. Other factors, such as temperature and temperature coefficient of resistance, can also impact resistance.
What are 4 things that influence resistance in a wire?
The four main factors that influence resistance in a wire are the material of the wire, the length of the wire, the cross-sectional area of the wire, and the temperature of the wire. These factors determine how easily electrons can flow through the wire and affect its overall resistance.
What are three things resistance of a wire depends on?
The resistance of a wire depends on its length - longer wires have higher resistance. It also depends on the material of the wire - materials with higher resistivity have higher resistance. Lastly, the cross-sectional area of the wire affects resistance - larger cross-sectional areas have lower resistance.
Does the temperature of the wire affect the current?
Yes, the temperature of the wire can affect the resistance of the wire, which in turn can affect the current flowing through it. As the temperature increases, the resistance of the wire also increases, which can reduce the current flow.
Three factors that affect the resistance of a copper wire -?
There are three main factors that affect the resistance of a copper wire: Length of the wire: The resistance of a wire is directly proportional to its length. As the length of the wire increases, the resistance also increases. This is because the longer the wire, the more obstacles (collisions with electrons) the current has to overcome, resulting in higher resistance. Cross-sectional area of the wire: The resistance of a wire is inversely proportional to its cross-sectional area. As the cross-sectional area of the wire increases, the resistance decreases. This is because a larger cross-sectional area provides more space for the flow of electrons, reducing the resistance. Resistivity of the material: The resistance of a wire is also dependent on the resistivity of the material it is made of. Resistivity is an inherent property of the material and is a measure of how much the material opposes the flow of electric current. Copper has a relatively low resistivity compared to other metals, making it a good conductor and suitable for wiring applications. The relationship between these factors and the resistance of a copper wire can be expressed by the formula: R = ρ × (L / A) Where: R is the resistance of the wire ρ (rho) is the resistivity of the material (in this case, copper) L is the length of the wire A is the cross-sectional area of the wire By adjusting these three factors, you can control and manipulate the resistance of a copper wire to suit your specific needs in electrical and electronic applications.

Does the diameter of the wire affect resistance?
Yes. Other things being equal, a thicker wire has less resistance.

How does the thickness of the wire affect resistance?
A thicker wire has less resistance than a thinner wire.

Yes, the temperature of the wire can affect the resistance of the wire, which in turn can affect the current flowing through it. As the temperature increases, the resistance of the wire also increases, which can reduce the current flow.
How does the cross sectional area of wire affect resistance?
Other things being equal, more cross-sectional area will cause less resistance.

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.
Do bends in a wire affects its electrical resistance?
Unless the wire is broken, a bent wire should still be able to conduct electricity as well as a straight one.
How Does the length of the wire affect its resistance?
As the length of the wire increases, the resistance also increases. This is because a longer wire offers more opposition to the flow of electrical current compared to a shorter wire. Resistance is directly proportional to length, so doubling the length of the wire will double its resistance.
What increases resistance in a wire?
Current (measured by an ammeter) and Voltage (measured by a voltmeter) R= V/I Resistance equals voltage divided by current ================================ That's wonderful, but the measurement doesn't "affect" the resistance of the wire. The factors that do "affect" the resistance ... i.e. determine what the resistance will be ... are -- substance of which the wire is composed -- dimensions of the wire: thickness and length.
