STANDARD Physics Atomic Structure and Current MCQ Question
In an atom electrons revolves around the nucleus along a path of radius 0.72 Å making 9.4 × 10¹⁸ revolution per second. The equivalent current is (e = 1.6 × 10⁻¹⁹)
1.2 A
1.5 A
1.4 A
1.8 A
Correct Answer
Detailed Explanation
The equivalent current I is given by I = e × v, where v is the frequency of revolution. Substituting the values, I = 1.6 × 10⁻¹⁹ × 9.4 × 10¹⁸ = 1.504 A, approximately 1.5 A.
