Question

write the Dimensional formula of L/R
​

Answer 1

Answer:

From equation (i), we get that the dimensional formula is R is [R]=[V][i]=[ML2T−3I−1][I]=[ML2T−3I−2]. ⇒[R]=[ML2T−3I−2] ….. (ii). Let us now calculate the dimensional formula of inductance L.

Answer 2

It can be easily worked out, if you know that L has unit Weber/Ampere and Resistance has unit ohm

Dimensional formula of L is [M¹L²C−²T0]

Dimensional formula of R is [M¹L²C−²T−¹]

So Dimensional Formula of L/R should be [T¹]
