The resistance of a wire of length willl be 6.2 ×10⁻⁵ ohm. The length, temperature, and thickness are the factors that affect the resistance of a material.
What is resistance?
Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire.
The value of resistance is directly propotional to length and inversly propotional to the area or thickness of the wire.
The value of the area of the wire is;
A=0.0314 mm
The relation of resistance with length and thickness is given by ;
[tex]\rm R= \frac{\rho L}{A} \\\\R= 3 \times 10^{-6}\frac{0.65}{0.0314} \\\\ R= 6.2 \times 10^{-5} \ ohms[/tex]
Hence, the resistance of a wire of length willl be 6.2 ×10⁻⁵ ohm.
