In the same way as you made sure that the chemical elements balanced on both sides of a chemical reaction equation, so also the physical dimensions balance.
Dimensional consistency is symbolic calculations that involves physical measurements. In physics equations, it is used in calculating the frequency.
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
[Young's Modulus] = M1L-1T-2 __> this is the dimensional formula
no
no
A dimensional check in an equation can provide a quick check about the possible correctness of the equation. For example, if you are supposed to calculate a speed, the dimensions of the result MUST be of the form [distance] / [time] (or something that you can simplify to distance/time). If it doesn't, the formula is wrong. If it does, it MIGHT be correct.
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
