Question

The drift velocity of the electrons is given by, where \(n\) is number of electrons per unit volume, \(I\) is the current, \(e\) is charge on electron and \(A\) is area:

• A. \(v_d=\dfrac{I}{nAe}\)
• B. \(v_d=\dfrac{ne}{IA}\)
• C. \(v_d=\dfrac{Ie}{nA}\)
• D. \(v_d=\dfrac{neA}{I}\)

Hint:

For drift velocity, remember \(I=nAe v_d\), so \(v_d=\frac{I}{nAe}\).

Answer 1

The Correct Option is A
