Consider a wire of length 0.1 m with an area fo cross section `1 mm^2` connected to 5V. Find the current flowing through the metallic wire where `mu = 5xx10^(-6) m^2`
`V_1 s^(-1), e = 1.6xx10^(-19) C, and n = 8xx10^(28) m^(-3).`

Explanation

To find the current flowing through the metallic wire, we will use the following steps:

### Step 1: Write down the given data
- Length of the wire (L) = 0.1 m
- Area of cross-section (A) = 1 mm² = \(1 \times 10^{-6} \, \text{m}^2\)
- Potential difference (V) = 5 V
- Mobility (μ) = \(5 \times 10^{-6} \, \text{m}^2/\text{V s}\)
- Charge of an electron (e) = \(1.6 \times 10^{-19} \, \text{C}\)
