What does Q mean in physics?
q is the symbol used to represent
charge
, while n is a positive or negative integer, and e is the electronic charge, 1.60 x 10
– 19
Coulombs.
What is Q vector space?
We’ve just noted that R as a vector space over Q contains a set of
linearly independent vectors of size n + 1
, for any positive integer n. Hence R cannot have finite dimension as a vector space over Q. That is, R has infinite dimension as a vector space over Q.
What is current formula?
Current is usually denoted by the symbol I. Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm’s law is
I = V/R.
What is the formula of charge?
| I = I = Q ÷ t | Q = It Q = I x t | t = t = Q ÷ I |

What is the unit of charge?
Coulomb
, unit of electric charge in the metre-kilogram-second-ampere system, the basis of the SI system of physical units. It is abbreviated as C. The coulomb is defined as the quantity of electricity transported in one second by a current of one ampere.
What is dimensional formula give example?
A formula that represents a physical quantity in terms of fundamental units along with appropriate dimensions within parenthesis or square bracket is known as a dimensional formula. e.g., : Dimensional formula for force is
(M1L1T-2)

What is dimensional formula of distance?
Distance travelled in the nth second by a particle moving with uniform acceleration, Using equation of motion, s=u+a2(2n−1) u is the velocity, therefore, all the dimensions will be in velocity. Hence,
[M0L1T0]
is the dimensional formula of distance travelled in nth second by a particle moving with uniform acceleration.
What is dimensional formula of current?

What is dimensional formula and dimensional equation class 11?
Dimensional Formula is the
expression which shows how and which of the
base quantities represent the dimensions of a physical quantity. Dimensional Equation is an equation obtained by equating a physical quantity with its dimensional formula.
