Question

Identify the dimension of electric potential,

• A. $L^{2}M{T}^{-3}{I}^{-1}$
• B. $L^{1}M{T}^{-2}{I}^{-1}$
• C. $L^{-2}M{T}^{-2}{I}^{-1}$
• D. none of the above

Answer 1

The correct option is A $L^{2}M{T}^{-3}{I}^{-1}$

Work done $=$ charge $\times$ potential difference

or Force $\times$ distance $=$ (current\times time)$\times$ potential difference

or $\left[ML{T}^{-2}\right]\times \left[L\right]=\left(\right[IT\left]\right)\left[V\right]$

or $\left[V\right]=\left[M{L}^2{T}^{-3}{I}^{-1}\right]$
