Hence, the dimensional formula for electric current density is [M0L−2T−1Q].

## What is the dimension formula of electric current?

Dimensional Formula:

Physical quantity | Unit | Dimensional formula |
---|---|---|

Electric conductance (1/resistance) | Ohm ^{–}^{1} or mho or siemen |
M ^{–}^{1}L ^{–}^{2}T ^{3}I ^{2} |

Electric conductivity (1/resistivity) | siemen/metre or Sm ^{–}^{1} |
M ^{–}^{1}L ^{–}^{3}T ^{3}I ^{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?

## 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.

## Does current have dimension?

Now, the dimensional formula for current is **[M0L0T−1Q]**.

## What is the dimensional formula of frequency?

Therefore, frequency is dimensionally represented as **[M ^{} L^{} T^{–}^{1}]**.

## How do you find the current dimension?

**Dimensional Formula of Current**

- M = Mass.
- I = Current.
- L = Length.
- T = Time.

## What is the dimension of power?

## What is the dimension of electric flux?

Therefore, the electric flux is dimensionally represented as **[M ^{1} L^{3} T^{–}^{3} I^{–}^{1}]**.

## What is dimension of Newton?

Force (Newton) = Mass of body × Acceleration. Or, F = [M^{1} L^{} T^{}] × [M^{} L^{1} T^{–}^{2}] = M^{1} L^{1} T^{–}^{2}. Therefore, Newton is dimensionally represented as **M ^{1} L^{1} T^{–}^{2}**.
