Question

which of the following dimensions will be same as time L/R OR C/L OR LC OR R/L what is L ?????
pls answer

Answer 1

The dimension of L/R is same as time.

R - Resistance ; L - Inductance.

If you need to find dimension of L/R

Multiply and divide ω(angular velocity) on numerator and denominator.

L/R = Lω / Rω

But, Lω = X (Inductive reactance/Resistance)

So dimension of R and Lω is cancelled and only ω is left in denominator.

Since unit of ω is s⁻¹ , unit of 1/ω = second
