Hence, the dimensional formula for electric current density is [M0L−2T−1Q].
What is the dimension formula of electric current?
|Physical quantity||Unit||Dimensional formula|
|Electric conductance (1/resistance)||Ohm –1 or mho or siemen||M –1L –2T 3I 2|
|Electric conductivity (1/resistivity)||siemen/metre or Sm –1||M –1L –3T 3I 2|
|Electric charge or quantity of electric charge (current × time)||coulomb||IT|
What is the MLT of current?
Originally Answered: What is the dimensional formula for electric current in the form of MLT? The voltage between two points is the work done per unit of charge in moving a charge between the two points. So voltage = work/charge, and work = force x distance and force = mass x acceleration.
What is dimension of electric charge?
|Another Metric (SI) Equivalent with More Basic Units||1.602176565×10-19 ampere seconds|
|Standard Uncertainty||± 3.5×10-27 coulombs|
|Metric (SI) Dimensions||time × electric-current|
What is dimension formula?
Hint – Dimension formula is the expression for the unit of a physical quantity in terms of the fundamental quantities. The fundamental quantities are mass (M), Length (L) and time (T). A dimensional formula is expressed in terms of power of M, L and T. … These will specify the nature of the unit and not its magnitude.
Does current have dimension?
Now, the dimensional formula for current is [M0L0T−1Q].
What is the dimensional formula of frequency?
Therefore, frequency is dimensionally represented as [M L T–1].
How do you find the current dimension?
Dimensional Formula of Current
- M = Mass.
- I = Current.
- L = Length.
- T = Time.
What is the dimension of power?
Units and dimensions
|power||[M L2 T–3]||watt|
|viscosity, dynamic||[M L–1 T–1]||pascal-second|
|viscosity, kinematic||[L2 T–1]||square meter per second|
|specific heat||[L2 Q–1 T–2]||joule per kilogram-kelvin|
What is the dimension of electric flux?
Therefore, the electric flux is dimensionally represented as [M1 L3 T–3 I–1].
What is dimension of Newton?
Force (Newton) = Mass of body × Acceleration. Or, F = [M1 L T] × [M L1 T–2] = M1 L1 T–2. Therefore, Newton is dimensionally represented as M1 L1 T–2.
