A copper wire of area of cross-section $2 × 10^{-6} m^2$ and electron density $10^{28} m^3$ carries a current of 1.6 A. Time taken by an electron to drift from one end of a 1.0 m long wire to its other end will be |
$2 × 10^3 s$ $10^3 s$ $2 × 10^{-3} s$ $1 × 10^{-3} s$ |
$2 × 10^3 s$ |
The correct answer is Option (1) → $2 × 10^3 s$ |
