**Q.No.13.2: - Do bends in a wire affect its electrical resistance?**

**Ans: -**The resistance of wire is

R =
ρ.L/A

Where “ρ” is the
resistivity of the conductor, L is the length and A is the area of cross
section of the wire. So according to this equation we can say that bends in a
wire will never affect the electrical resistance because we bending the wire
its ρ, L and A remain same so its resistance remain same.
