The average drift speed of conduction electrons in a copper wire of cross-sectional area $1.0 \times 10^{-7} m^2$ carrying a current of 1.5 A. (Assume the density of conduction electrons to be $\left.9 \times 10^{28} / m^3\right)$ |
$2.08 \times 10^{-4} m / s$ $1.04 \times 10^{-3} m / s$ $6.96 \times 10^{-3} m / s$ $2.9 \times 10^{-4} m / s$ |
$1.04 \times 10^{-3} m / s$ |
The correct answer is Option (2) → $1.04 \times 10^{-3} m / s$ |
