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
y(young's modulus of rigidity)=stress/strain now strain is dimensionless hence y=stress y=M L-1 T-2
[Young's Modulus] = M1L-1T-2 __> this is the dimensional formula
