Electric Current, Drift Velocity & Current Density

A flow of 10710^{7} electrons per second in a conducting wire constitutes a current of

Show answer and solution

Answer: (a)

  1. Current I=qt=netI = \dfrac{q}{t} = \dfrac{ne}{t}
  2. I=107×1.6×10−19=1.6×10−12 AI = 10^{7} \times 1.6 \times 10^{-19} = 1.6 \times 10^{-12}\text{ A}
  3. So the answer is (a) 1.6×10−12 A1.6 \times 10^{-12}\text{ A}.
