The dimension of $R$ (Resistance) is:

The physical quantities not having the same dimensions are:

The position of a particle at time $t$ is given by the equation $x(t) = \frac{v_0}{A}(1 - e^{-At})$, where $v_0$ is a constant and $A > 0$. The dimensions of $v_0$ and $A$ respectively are:

Dimensions of charge are
