Electric conductance (1/resistance) Ohm 1 or mho or siemen M 1L 2T 3I 2
Electric conductivity (1/resistivity) siemen/metre or Sm 1 M 1L 3T 3I 2
Electric charge or quantity of electric charge (current × time) coulomb IT
Electric current ampere I

## What is the MLT of current?

Originally Answered: What is the dimensional formula for electric current in the form of MLT? The voltage between two points is the work done per unit of charge in moving a charge between the two points. So voltage = work/charge, and work = force x distance and force = mass x acceleration.

## What is dimension of electric charge?

Metric (SI) Dimensions time × electric-current

## What is dimension formula?

Hint – Dimension formula is the expression for the unit of a physical quantity in terms of the fundamental quantities. The fundamental quantities are mass (M), Length (L) and time (T). A dimensional formula is expressed in terms of power of M, L and T. … These will specify the nature of the unit and not its magnitude.
