resistance?

Question

help me with this

how will i calculate for the resistance of a Nichrome wire 0.50 mm in diameter and 1.25 m long?

Answer 1

Here's the resistance equation:

R = rho * L / A

R: Resistance
rho: Resistivity
L: Length of wire
A: Area of wire

You'll need to look up the resistivity (rho) of Nichrome, but after that, it's all plug and chug.
