Current Electricity question

2023 · 8 Apr · Shift 2 · Q58

JEE MainPhysicsCurrent ElectricityNumerical+4 / −1
The number density of free electrons in copper is nearly 8×1028 m−38 \times 10^{28} \mathrm{~m}^{-3}8×1028 m−3. A copper wire has its area of cross section =2×10−6 m2=2 \times 10^{-6} \mathrm{~m}^{2}=2×10−6 m2 and is carrying a current of 3.2 A3.2 \mathrm{~A}3.2 A. The drift speed of the electrons is ‾×10−6ms−1\underline{\hspace{2cm}}\times 10^{-6} \mathrm{ms}^{-1}​×10−6ms−1
