Question

Which of the following quantities has the SI unit kg m² s^-3

A^-2?

• A. Resistance
• B. Inductance
• C. Capacitance
• D. Magnetic Flux

Answer 1

Answer: (A)

Resistance

Answer 2

$m^{2}s^{- 3}A^{- 2} = \lbrack ML^{2}T^{3}A^{- 2}\rbrack = \frac{\lbrack ML^{2}T^{- 2}\rbrack}{\lbrack A^{2}T\rbrack} = \frac{\lbrack ML^{2}T^{- 2}\rbrack}{\lbrack AT\rbrack\lbrack A\rbrack} = \frac{Work}{Ch\arg e \times current} = \frac{Voltage}{Current} = {Re}sis\tan ce$
