# What affects the resistance of an electric conductor?

The material from which the conductor is made, the length of the conductor, the diameter of the conductor and the temperature of the conductor are all things that impact its resistance.

### What is a principal of resistance?

basically it slows down the flow of current. max resistace = no current min. resistance = fullcurrent. Answer I think you mean the principle, not 'principal', of resistance! Resistance is a natural property of any conducting material, and is determined by the length, cross-sectional area, and resistivity of that material. As resistivity is affected by temperature, temperature indirectly affects resistance. Resistance is directly proportional to length -e.g. double the length of a conductor, you double…

### Why does Resistance decrease in thin wire?

Area of cross section: Resistance R is inversely proportional to the area of cross section ( A) of the conductor. This means R will decrease with increase in the area of conductor and vice versa. More area of conductor facilitates the flow of electric current through more area and thus decreases the resistance. This is the cause that thick copper wire creates less resistance to the electric current.

### What affects the resistance of a conductor?

The length and the material that the conductor is made from. Different wire sizes have different ohm/foot. The longer the length of the conductor the higher the ohms/foot. Temperature also affects the resistance. Silver has the least resistance, followed by Copper, then Gold, then Aluminum. Here are some published resistances in micro ohm-cm: Silver - 1.6 Copper - 1.7 Gold - 2.2 Aluminum - 2.7

### What three factors can alter the resistance of an electrical conductor?

1) What materials the conductor is made of; 2) the average cross-sectional area along the length of the conductor; 3) the temperature of a conductor also affects its resistance; 4) the length of the conductor is also very important. Generally, the longer the conductor, the higher its resistance. Your students' course materials can probably give you a better answer than mine, or at least you'll know it is the right one.

### What factors contribute to the electrical resistance of a conductor?

1) What materials the conductor is made of; 2) the average cross-sectional area along the length of the conductor; 3) the temperature of a conductor also affects its resistance; 4) the length of the conductor is also very important. Generally, the longer the conductor, the higher its resistance. Your students' course materials can probably give you a better answer than mine, or at least you'll know it is the right one.

### How Magnetism effect resistance?

Magnetism does not affect the resistance of a conductor. The factors affecting resistance are the conductor's length, cross-sectional area, and resistivity. As resistivity is affected by temperature, temperature indirectly affects resistance. However, the changing magnetic field surrounding a conductor carrying an AC current causes the current to flow closer to the surface rather than being distributed throughout the cross-section of the conductor. The greater the frequency, the greater this effect. This has the equivalent effect…

### What are four factors that determine resistance?

There are three, not four, factors that determine the resistance of a conductor. These are the length of a conductor, its cross-sectional area, and its resistivity. As resistivity is affected by temperature, you could say that temperature indirectly affects resistance but, strictly, temperature is affecting the resistivity not the resistance -which is why it is not considered a 'fourth' factor. So, resistance = resistivity x (length/area)

### Why is the electric heating conductor of an electric iron made up of alloy rather than a pure metal?

### What is the resistance of a conductor directly proportional to?

The resistance of a conductor is directly proportional to several different factors. Here is a list of some of them: the cross-sectional area or thickness of the conductor; the overall length of the conductor; the resistivity of the material from which the conductor has been made - note that this is often dependant on its actual temperature; the actual temperature the conductor reaches after a steady electric current has been passing through it for sufficient…

### How do you decide cable size for required load?

i=v/R and R=rho.L/A . by analysing these fourmulas we find the size . here i is electric current in the conductor to flow or load current to flow . v is the voltage across the conductor , R is the resistance of the conductor . L is the length of the conductor ,rho is a constant of a material called specific resistance here the the material is the material of the conductor , A is…

### Why conductors offer resistance?

Yes , all conductors have some amount of resistance although it varies depending on the material that is conducting the electricity . Copper has a very low resistance, and aluminum has a slightly higher ( but still quite low ) resistance . This is why they are used as electrical conductors. Conductor resistance results in voltage drop over the conductor and power loss, manifested as heating of the conductor . Therefore , you want as…

### Do conductors have resistance?

Yes, all conductors have some amount of resistance although it varies depending on the material that is conducting the electricity. Copper has a very low resistance, and aluminum has a slightly higher (but still quite low) resistance. This is why they are used as electrical conductors. Conductor resistance results in voltage drop over the conductor and power loss, manifested as heating of the conductor. Therefore, you want as low a conductor loss as is reasonably…

### What are the four factorws affecting electrical resistance?

There are really only three things that affect electrical resistance. They are the length and cross-sectional area of a conductor and its resistivity. However, resistivity depends not only on the material from which the conductor is manufactured, but upon its temperature. So you could say that temperature indirectly affects resistance via its resistivity.

### What is the difference between conductor resistance and insulation resistance?

In the general sense, a conductor's resistance is usually in the milliohm to low ohms range, whereas an insulator's resistance is in the megohm range. For an insulated conductor, the resistance of the conductor is directly proportional to its length, whereas its insulation resistance is inversely proportional to the length of the conductor.

### Amps decrease resistance increase?

yes Answer No! Resistance is determined by the length, cross-sectional area, and resistivity of a conductor. Resistivity is, in turn, affected by temperature -so temperature indirectly affects resistance. These are the only factors that affect resistance. Voltage and current have no direct effect whatsoever on resistance. Current can affect resistance indirectly if it causes the conductor's temperature to increase. For AC circuits, 'skin effect', due to frequency, causes the current to flow towards the surface…

### What causes resistance to increase or decrease?
