How do you calculate the resistance of Nichrome wire?

Given: ρ=1.5 × 10−6 Ωm ρ = 1.5 × 10 − 6 Ω m is the resistivity of nichrome.

How do I calculate resistance per unit length?

FORMULA:-1) resistance of the wire,R=1/m Where R=resistance of the wire,m=slope of the graph of current versus potential difference. 2)resistance per unit length=R/LWhere L=the length of the experimental wire.

What will be the length of a Nichrome wire?

Since resistance R=rho×l/A where l is the length of the wire. l2=240 cm.

What is the relationship between the length of the Nichrome wire and resistance?

As the length of wire increases, the resistance increases.

How do you calculate resistance of a wire?

Specific Resistance (”ρ”) is a property of any conductive material, a figure used to determine the end-to-end resistance of a conductor given length and area in this formula: R = ρl/A. Specific resistance for materials are given in units of Ω-cmil/ft or Ω-meters (metric).

What is the unit of resistance per unit length?

Therefore, Resistance per unit length is the ratio of specific resistance or resistivity to the area of cross-section of given conductor in Ohm per meter. This parameter is mostly calculated in power system analysis, transmission, and distribution systems.

How do you calculate resistance per meter?

Engineers often ask how to calculate the resistance of a cable, there is a very simple formula that works well within an ohm or so with copper cable. 19 ÷ by 2.5mm² will give you 7.6 ohms per km. ÷ by 1000 for resistance per meter.

What is the length of Nichrome wire of resistance 5 ohm?

So, required length will be 160cm.

What will be the resistivity of a metal wire of 2m length and 0.6 mm in diameter if the resistance of the wire is 50 ohm?

Resistivity of the wire is 7.065 × 10^-8 Ω m. Hope it helps…!!!

How do you find the length of a wire using resistance?

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

How do you calculate the resistance of a wire?

What is the resistance of 22 gauge wire?
