What is the dimensions of impedance ?
Options
- A( [ ML ^2 ~T ⁻³ ~A ⁻² ] )
- B( [ M ⁻¹ ~L ⁻² ~T ^3 ~A ^2 ] )
- C( [ ML ^3 ~T ⁻³ ~A ⁻² ] )
- D( [ M ⁻¹ ~L ⁻³ ~T ^3 ~A ^2 ] )
Correct answer
A. ( [ ML ^2 ~T ⁻³ ~A ⁻² ] )
Step-by-step solution
Impedance has the same dimensions as that of a resistance ( aligned & Resistance R= Voltage V current I & = [ ML ^2 ~T ⁻³ I ⁻¹ ] [ I ] = [ ML ^2 ~T ⁻³ I ⁻² ] aligned )
