Question

In a hydrogen atom an electron makes 6.6x10${}^{15}$ rev /sec, around the nucleus. Then its equivalent current is

• A. 1) $1.06\times 10$${}^{-3}$amp
• B. 2) $4\times 10$${}^3$amp
• C. 3) $4.6\times 10$${}^{-4}$amp
• D. 4)$1.06\times 10$${}^{-4}$amp

Answer 1

The correct option is A 1) $1.06\times 10$${}^{-3}$amp

$I=\frac{Q}{T}$

$=6.6\times {10}^{15}\times 1.6\times {10}^{-19}$

$=66\times 16\times {10}^{-6}$

$=1.056\times {10}^{-3}amp$
