Divine Electric Current Dimensional Formula
The rate of flow of charge through any cross-section of a wire is called electric current flowing through it.
Electric current dimensional formula. 92 rows In mechanics the length mass time temperature and electric current are taken as three base dimensions and meter kilogram second ampere kelvin mole and candela are the fundamental units. Resistance R Voltage Current -1. Units and Measurements Class 11 MCQs Questions with Answers.
For example since F qE charge q in coulombs 1 coulomb. Dimensional Formula of Magnetic Field The dimensional formula of a magnetic field can be defined as the representation of units of a magnetic field in terms of fundamental physical quantities with appropriate power. Since all the dimensions in the three terms are the same the equation is correct.
In physics the Poynting vector represents the directional energy flux the energy transfer per unit area per unit time of an electromagnetic fieldThe SI unit of the Poynting vector is the watt per square metre Wm 2It is named after its discoverer John Henry Poynting who first derived it in 1884. Good physics equations and good students balance their MLTs. B quantities such as length mass time electric current thermodynamic temperature amount of substance and luminous intensity.
Dimensions and Dimensional Analysis. Where the formula has the dimensions in it ie MASS LENGTH TIMETEMPERATURE CURRENT denoted by M L T K A respectively. Dimensional formula of any physical quantity is the expression in which the fundamental physical quantities are raised to specific powers.
Electric charge is a stand-alone or fundamental dimension in that it is not expressible as a combination of other dimensions except to define it in terms of its dynamical properties. Dimensional Analysis ALL units are expressed in terms of three basic quantities mass M length L and time T expressed in Kilogram Meter and Second respectively. Electric current I q t.
The dimensional formula of current density is given by M0 L-2 T0 I1 Where standard unit mass is represented as M current by I length by L and time by T. The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space its direction being that of the motion of the positive charges at this point. C quantities such as pounds dollars and rupees.
