the formula showing the relation between the unit of any physical quantity n the unit of fundamental physical quantity is called dimensional formula.........of dat quantity
The dimensional formula of current density (J) is derived from the definition of current density as current per unit area. Current (I) has a dimensional formula of ([I]), and area (A) has a dimensional formula of ([L^2]). Therefore, the dimensional formula of current density is ([J] = [I][L^{-2}] = [I][L^{-2}]).

Resistance = V/I Dimensional formula for V ML2T -3A -1 Dimensional formula for I A Dimensional formula for R= ML2T -3A -1 / A = ML2T -3A -2
The dimensional formula of current density (J) is derived from the definition of current density as current per unit area. Current (I) has a dimensional formula of ([I]), and area (A) has a dimensional formula of ([L^2]). Therefore, the dimensional formula of current density is ([J] = [I][L^{-2}] = [I][L^{-2}]).
[Young's Modulus] = M1L-1T-2 __> this is the dimensional formula
The dimensional formula of electric current is [I] = [A], where I represents current and A represents ampere.
The dimensional formula for angular velocity is T-1, where T represents time.
The dimensional formula of depression is that it has the same dimensions as pressure, which is force per unit area. Thus, the dimensional formula of depression is [ML^-1T^-2].
