The dimensions of resistance are the same as (where h is the Plank's constant and e is the charge)

Options

  1. Ah 2 e 2
  2. Bh 2 e
  3. Ch e 2
  4. Dh e

Correct answer

C. h e 2

Step-by-step solution

Resistance, R = V i = W q i = M L 2 T - 2 A 2 T R = M L 2 T - 3 A - 2 h e 2 = M L 2 T - 1 A T 2 = M L 2 T - 3 A - 2
