What is the dimensional formula of current in physics?
Dimensional Formula of Current. The dimensional formula of current is given by, [M 0 L 0 T 0 I 1 ] Where, M = Mass. I = Current. L = Length.
What is the fundamental unit of current?
CURRENT (Denoted by I ) Has a relation formula with charge defined as [math]I=Q/Tmath] where Q is charge (S.I. unit C [Coulomb]) and T is time (S.I. unit s [second]) So from here we derive unit of current to be [math]Coulomb/second[/math] But it has a different fundamental unit Ampere After Andre Marie Ampere Definition:
What is a dimensional equation?
A dimensional equation is an equation that relates fundamental units and derived units in terms of dimensions. 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.
What is the dimensional formula for fundamental units?
The expression depicting the powers to which the fundamental units are to be raised to obtain one unit of a derived quantity is known as the dimensional formula. It is given as, Q = M a L b T c, where, M, L, T are base dimensions with respective exponents a, b and, c. and Q is the physical quantity.
