- D \(\left[\begin{array}{llll}\mathrm{L}^{2} & \mathrm{M}^{1} & \mathrm{~T}^{0} & \mathrm{I}^{1}\end{array}\right]\)
Answer & Solution
Correct Answer
(C) \(\left[\begin{array}{lll}\mathrm{L}^{-1} & \mathrm{M}^{0} & \mathrm{~T}^{0} & \mathrm{I}^{1}\end{array}\right]\)
Step-by-step Solution
Detailed explanation
\(H = \frac{\text{Current}}{\text{Length}}\) \([\text{H}] = \frac{[\text{I}]}{[\text{L}]} = [\text{L}^{-1}\text{I}^{1}] = [\text{M}^{0}\text{L}^{-1}\text{T}^{0}\text{I}^{1}]\)
