Write the dimensional formula of potential.
The correct equation of motion is :
(a) v=u+aS (b) v=ut+a
(c) S=ut+12at (d) v=u+at
Let I = current through a conductor, R = its resistance and V = potential difference across its ends. According to Ohm's law, product of two of these quantities equals the third. Obtain Ohm's law from dimensional analysis. Dimensional formulae for R and V are ML2I−2T−3 and ML2T−3I−1 respectively.
Statements: R > S ≥ T ≥ U; V < T
Conclusions: I. V ≥ U II. V < R
