Question

If L and R denote inductance and resistance, respectively, then the dimension of L/R is –

• A. M⁰L⁰T
• B. M⁰L⁰T⁰
• C. M²L⁰T²
• D. MLT²

Answer 1

Answer: (A)

M⁰L⁰T

Answer 2

$\left\lbrack \frac{L}{R} \right\rbrack = \left\lbrack \frac{L}{R} \right\rbrack = \frac{\lbrack M^{1}L^{2}T^{- 2}A^{- 2}\rbrack}{\lbrack ML^{2}T^{- 3}A^{- 2}\rbrack} = \lbrack T\rbrack$
