1.Units, Dimensions and Measurement
medium
Which of the following units denotes the dimensions $\frac{{M{L^2}}}{{{Q^2}}}$, where $Q$
denotes the electric charge?
A$weber $ $(Wb)$
B$\frac{{Wb}}{{{m^2}}}$
C$henry$ $(H)$
D$\;\frac{H}{{{m^2}}}$
Solution
Mutual indenctance $=\frac{\phi}{I}= \frac{BA}{I}$
$\left[\right.$ Henry] $=\frac{\left[M T^{-1} Q^{-1} L^{2}\right]}{\left[Q T^{-1}\right]}= M L^{2} Q^{-2}$
$\left[\right.$ Henry] $=\frac{\left[M T^{-1} Q^{-1} L^{2}\right]}{\left[Q T^{-1}\right]}= M L^{2} Q^{-2}$
