Answer» Correct Answer - D Resistance `R=("potential di fference")/("Current")=V/i=W/(qi)` (`:.` Potential difference is equal to work done per unit charge) So, Dimension of `R` `=(["Dimension of work"])/(["Dimension of charge"]["Dimension of current"])` `=([ML^(2)T^(-2)])/([IT][I])=[ML^(2)T^(-3)I^(-2)]`  |
