If C and V represent capacity and voltage respectively then what are the dimensions of λ where C / V = λ ?

Options

  1. AM - 2   L - 4   I 3   T 7
  2. BM - 2   L - 3 I 2   T 6
  3. CM - 1   L - 3 I - 2   T - 7
  4. DM - 3   L - 4 I 3   T 7

Correct answer

A. M - 2   L - 4   I 3   T 7

Step-by-step solution

λ = C V = Q / V V = Q V 2 V =   w o r k   Q λ = Q 3 w o r k 2 = I t 3 F . s 2 = I 3 T 3 ML 2 T - 2 2 = M - 2 L - 4 I 3 T 7
