Therefore, Electromotive Force or EMF is dimensionally represented as [M1 L2 T-3 I-1].
What is the definition of 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 the formula for electromotive force?
The emf is equal to the work done on the charge per unit charge (ϵ=dWdq) when there is no current flowing. Since the unit for work is the joule and the unit for charge is the coulomb, the unit for emf is the volt (1V=1J/C).
What is the dimensional formula of Omega?
Mathematically, Angular speed (ω) = 2π/ Time.
What are the 7 fundamental dimensions?
In total, there are seven primary dimensions. Primary (sometimes called basic) dimensions are defined as independent or fundamental dimensions, from which other dimensions can be obtained. The primary dimensions are: mass, length, time, temperature, electric current, amount of light, and amount of matter.
What does dimensional mean?
The definition of dimensional is something a shape that can be measured. An example of dimensional is a physical object with length, width and depth, like a table. adjective.
What is SI unit of EMF?
It is commonly measured in units of volts, equivalent in the metre–kilogram–second system to one joule per coulomb of electric charge. In the electrostatic units of the centimetre–gram–second system, the unit of electromotive force is the statvolt, or one erg per electrostatic unit of charge.27 мая 2020 г.
What is work formula?
Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d).

What is the dimension of Curie?
Curie Per Liter (Ci/l) has a dimension of L-3T-1 where L is length, and T is time. It can be converted to the corresponding standard SI unit Bq/m3 by multiplying its value by a factor of 3.7E+013.
What is difference between Dimension and Unit?
Dimensions are physical quantities that can be measured, whereas units are arbitrary names that correlate to particular dimensions to make it relative (e.g., a dimension is length, whereas a meter is a relative unit that describes length).
How many dimensions are there?
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
What does T stand for in dimensions?
Teaspoon = t. or tsp. Tablespoon = T. or tbsp. Cup = C. or c. Pint = pt.
