Question 202: Units , Dimensions and Error Analysis

Question

Let $\ell $, r, C and V represent inductance, resistance, capacitance and voltage, respectively. The dimension of ${\ell  \over {rCV}}$ in SI units will be :

Accepted Answer

$\left[ {{\ell  \over r}} \right] = $ T
[CV] $=$ AT
So,   $\left[ {{\ell  \over {rCV}}} \right]$ = ${T \over {AT}}$ = [A
