Determine the resistance of a 10 cm long nichrome wire if its cross-sectional area is 0.1 mm2.

Initial data: l (length of nichrome wire) = 10 cm; S (cross-sectional area of nichrome wire) = 0.1 mm ^ 2.

Reference data: ρ (resistivity of nichrome) = 1.1 Ohm * mm ^ 2 / m.

SI system: l = 10 cm = 10/100 m = 0.1 m.

The resistance of nichrome wire is determined by the formula: R = ρ * l / S.

Let’s perform the calculation: R = 1.1 * 0.1 / 0.1 = 1.1 Ohm.

Answer: The resistance of the nichrome wire is 1.1 ohm.
