what is the dimension of resistance....????

Dimension of resistance can be worked out by using Ohm's law

You know V = IR or R = V/I....(1)

The dimensional formalism of equation (1) can be written as follows

[R] = [V]/[I] = [W/q]/[I]  { since potential refers to work done(W) per unit charge }

So [R] = [w]/[qI] = [W]/[I²T]   { [I] = [q]/[T] where T stands for time }

thus [R] = [ML²T^-2]/[A²T]  {  dimension of current is taken as [A] }

  = [M¹L²T¹A^-2]  (ans)

thnkx....

thnkx dude....

thank you!!

• [M][L]² [T]^-3 [I]^-2
