Determine the resistance of a 80 cm long nickel wire with a cross section of 1 mm2.
| May 2, 2021 | education
Initial data: l (length of nickel wire) = 80 cm = 0.8 m; S (nickel wire cross section) = 1 mm2.
Reference values: ρ (nickelin resistivity) = 0.4 Ohm * mm2 / m.
You can determine the resistance of nickel wire using the formula: R = ρ * l / S.
Let’s calculate: R = 0.4 * 0.8 / 1 = 0.32 Ohm.
Answer: The resistance of the nickel wire is 0.32 ohm.
