You can quickly determine the resistance and conductance of a wire by using the Wire Resistance Calculator. After pressing the calculate button, this tool takes the material type, length, and area and speeds up the calculations to display the electrical properties of a wire in a short time.

**Wire Resistance Calculator:** Are you looking for a simple way to calculate the electrical characteristics of a certain wire? If that's the case, this calculator will be helpful. It specifies the resistance and conductance values for the specified wire material type. The straightforward step-by-step technique for calculating wire resistance, conductance, and formula is shown below. Also, be aware of the materials' resistivity and conductivity. Check out the wire resistance examples that have been solved.

The property of a wire that resists the flow of electric current is referred to as wire resistance. The resistance provided by a material per unit length for a given cross-sectional area is referred to as its resistivity. It is more difficult for current to flow through a material with a higher resistivity.

The amount of voltage required for electric current to flow is defined as electrical conductivity. Resistance and conductance are calculated using the following formulas

R = ρL/A

G = σA/L

R = 1/G

- Where, R = resistance
- ρ = resistivity of the material
- σ = conductivity
- L = wire length
- A = cross-sectional area of the wire
- G = conductance

Low resistance materials like copper and aluminium are good for manufacturing electrical wire and cables.It's important to keep in mind that temperature affects resistance and conductivity.

The following factors influence a wire's resistance

- The length of the wire
- The cross-sectional area of the wire
- The nature of the wire's material
- The temperature of the material

**Question 1:** Determine the resistance and conductance of a material with a resistivity of 5 Ωm and a conductivity of 0.48 S/m. The length of the aluminium wire is 15 metres, and the cross-sectional area is 3 square metres.

**Solution:**

Given: Resistivity of the wire ρ = 5 Ωm

Conductivity of the wire σ = 0.48 S/m

Wire length L = 15 m

Cross-sectional area A = 3 m2

Resistance of the material R = ρL/A

R = (5 x 15)/3

= 25 Ω

Conductance G = 1/R

= 1/25

= 0.04

Hence, the resistance and Conductance of the wire is 25 Ω and 0.04 S.

**1. How does the wire length affect resistance?**

A wire's resistance is proportional to the wire's length. As a result, the longer the wire, the higher the resistance, because the electrons must travel a greater distance and encounter more collisions.

**2. How does the area of a wire affect resistance?**

The resistance of a wire is proportional to its cross-sectional area in inverse proportion. As a result, reducing the cross-sectional area of the wire increases its resistance.

**3. What is resistance and conductance of a wire?**

The resistance of a cable to electric current flow is measured in ohms, while conductance is the quantity of a wire's ability to conduct it.

**4. How can you find out how much resistance a wire does have?**

Calculate the resistance of each length of wire using R = V/I, where, R represents resistance, V represents voltage, and I represents current.

**5. How do you find out the length of a wire based on its resistance?**

You can estimate the overall length of the wire by dividing the resistance value for the entire wire by the resistance value for the 1 m length (in meters).
