What is the dimensional formula of electric potential or potential difference?
Or, P.D = [M1 L2 T–2] × [M L T1 I1]–1 = [M1 L2 T–3 I–1] . Therefore, the Potential difference is dimensionally represented as [M1 L2 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?
|Physical quantity||Unit||Dimensional formula|
|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.
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.
