Quick Answer: What is the dimensional formula of potential electric potential?

Contents

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

Or, P.D = [M1 L2 T2] × [M L T1 I1]1 = [M1 L2 T3 I1] . Therefore, the Potential difference is dimensionally represented as [M1 L2 T3 I1].

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 3I 1
Electric resistance (potential difference/current) ohm ML 2T 3I 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.
