Calculation of Cross-Sectional Area of the Nichrome Wire

To find the cross-sectional area of the nichrome wire, we can use the formula:

Resistance (R) = Resistivity (ρ) x Length (L) / Cross-Sectional Area (A)

Given: - Resistance (R) = 24 Ω - Length (L) = 4.8 m

We need to find the cross-sectional area (A) of the wire.

To calculate the cross-sectional area, we rearrange the formula as follows:

A = ρ x L / R

However, we don't have the value of the resistivity (ρ) of the nichrome wire. Unfortunately, the search results provided by You.com do not contain the necessary information to determine the resistivity of nichrome wire. Therefore, without the value of the resistivity, we cannot calculate the cross-sectional area of the wire.

If you have the resistivity value of the nichrome wire, please provide it, and I will be happy to help you calculate the cross-sectional area.
