Question:

The dimensions of Inductance/Resistance is same as the dimension of 

Options:

Time

Inductive reactance

Time inverse

Capacitance

Correct Answer:

Time inverse

Explanation:

LI = \(\frac{dε}{dt}\) ⇒ L = \(\frac{dε}{Idt}\)

IR = V ⇒ R = V/I

L/R =  \(\frac{Idε}{Vidt}\) 

Thus, L/R has dimensions of time inverse
