What is the dimensions of impedance?

View answer and explanation

Correct option: A

\mathrm{ML}^2 \mathrm{~T}^{-3} \mathrm{I}^{-2}

Option A (

\mathrm{ML}^2 \mathrm{~T}^{-3} \mathrm{I}^{-2}

) is correct because impedance has the same dimensions as resistance, which can be derived from Ohm's law and the definition of power.
