## What is the dimensional formula of electric potential or potential difference?

Or, P.D = [M^{1} L^{2} T^{–}^{2}] × [M^{} L^{} T^{1} I^{1}]^{–}^{1} = [M^{1} L^{2} T^{–}^{3} I^{–}^{1}] . Therefore, the Potential difference is dimensionally represented as **[M ^{1} L^{2} T^{–}^{3} I^{–}^{1}]**.

## How do you find the dimensional formula of potential?

The answer is a. The potential difference is the work done per unit charge. The dimensional formula for potential difference is **dimension of work/dimension of charge =dimensions of mass times acceleration times distance/ dimension for charge =M^1L^1T^-2L^1 / A^1T^1 = M^1 L^2 T^-3A^-1** HENCE OPTION “C” IS CORRECT.

## What are the dimension of electric potential?

Electric potential has the **dimension length squared mass per electric current time cubed**. The SI unit of electric potential is the volt, which is defined as a joule per coulomb. Another physical quantity with the same dimension is electromotive force.

## What is the dimensional formula of electric current?

Dimensional Formula:

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

Electric current | ampere |
I |

Electric dipole moment (charge × distance) | Cm | LTI |

Electric field strength or Intensity of electric field (force/charge) | NC ^{–}^{1}, Vm ^{–}^{1} |
MLT ^{–}^{3}I ^{–}^{1} |

Electric resistance (potential difference/current) | ohm | ML ^{2}T ^{–}^{3}I ^{–}^{2} |

## What is dimensional formula?

Dimensional formula (equation) (Definition) : **An equation, which gives the relation between fundamental units and derived units in terms of dimensions** is called dimensional formula (equation). In mechanics the length, mass and time are taken as three base dimensions and are represented by letters L, M, T respectively.

## What is electric potential write its dimension and derive expression for it?

Hint: The dimensional formula of electric potential can be found by using the dimensions of energy and charge, as electric potential is the work done per unit charge. … **V=Wq** , where V is electric potential, W is the work done by the electric field on charge and q is charge.
