Question

If $L$ and $R$ are respectively the inductance and resistance, then the dimensions of $\frac{L}{R}$ will be-

• A. $\mathbf{M}^{\mathbf{0}}\mathbf{L}^{\mathbf{0}}\mathbf{T}^{\mathbf{-}\mathbf{1}}$
• B. $\mathbf{M}^{\mathbf{0}}\mathbf{L}\mathbf{T}^{\mathbf{0}}$
• C. $\mathbf{M}^{\mathbf{0}}\mathbf{L}^{\mathbf{0}}\mathbf{T}$
• D. Cannot be represented in terms of M, L and T

Answer 1

Answer: (C)

$\mathbf{M}^{\mathbf{0}}\mathbf{L}^{\mathbf{0}}\mathbf{T}$

Answer 2

L/R = Time constant
