Estimate the average drift speed of conduction electrons in a copper wire of cross-sectional area `1.0xx10^(-7)m^(2)` carrying a current of `1.5xx10^(-19)`A. Assume the density of conduction electrons to be `9xx10^(28)m^(-3)`.

Explanation

To estimate the average drift speed of conduction electrons in a copper wire, we can use the formula for drift speed \( v_d \):

\[ v_d = \frac{I}{n \cdot e \cdot A} \]

where:
- \( I \) is the current (in Amperes),
