Calculate the electric field in a copper wire of cross-sectional area`2.0mm^(2)` carrying a current of 1A .The resistivity of copper `=1.7xx10^(-8)(Omega)m`.

Explanation

To calculate the electric field in a copper wire carrying a current of 1 A with a cross-sectional area of \(2.0 \, \text{mm}^2\), we can follow these steps:

### Step 1: Convert the cross-sectional area to square meters
The given cross-sectional area is \(2.0 \, \text{mm}^2\). We need to convert this to square meters:
\[ 2.0 \, \text{mm}^2 = 2.0 \times 10^{-6} \, \text{m}^2 \]
