Question

The current produced in wire when 10⁷ electron/sec are flowing in it

• A. 1.6 × 10^–26amp
• B. 1.6 × 10¹²amp
• C. 1.6 × 10²⁶amp
• D. 1.6 × 10^–12amp

Answer 1

Answer: (D)

1.6 × 10^–12amp

Answer 2

$i = \frac{Q}{t} = \frac{ne}{t} = 10^{7} \times 1.6 \times 10^{- 19} = 1.6 \times 10^{- 12}amp$
