Want this question answered?
1.dimensional formula for self inductance 2.a sphere has a mass of 12.2kg+or- 0.1 kg and radius 10cm +or- 0.cm the maximum percentage error in density is
no
no
the formula showing the relation between the unit of any physical quantity n the unit of fundamental physical quantity is called dimensional formula.........of dat quantity
It is a 3 dimensional object that has density and volume
Units are gm/cc or Kg/cu.m so M/L3 .

Resistance = V/I Dimensional formula for V ML2T -3A -1 Dimensional formula for I A Dimensional formula for R= ML2T -3A -1 / A = ML2T -3A -2
Resistance = V/I Dimensional formula for V ML2T -3A -1 Dimensional formula for I A Dimensional formula for R= ML2T -3A -1 / A = ML2T -3A -2
One way to calculate current is using ohms law; current equals voltage divided by resistance or: I=V/R Where I is current, V is voltage and R is resistance.
J = ρ.u Where J = Current Density (Ampere per meter square) ρ = Charge Density (Coulombs per cubic meter) u = Particles average drift velocity (meters per second)
[Young's Modulus] = M1L-1T-2 __> this is the dimensional formula
Inductance = Magnetic Flux/Current = [ML2T-2A-1]/[A] = [ML2T-2A-2] So, Dimensional Formula of Inductance = [ML2T-2A-2]
No mass does not equal density divided by volume but means multiplied by because that is six dimensional space and density is three dimensional space and mass volume is -3 dimensional space
Density current is where a warm current floats on top of a cold current.
The current element is directly proportional to the current density. The current density is the electric current per unit area of cross section.
Current is not scalar. Current is a vector quantity. For simplicity, in electric circuits, current is scalar because the direction is assumed to be one way or another, rather than three dimensional.
