What are the dimensions of impedance ?

Answer»

`[ML^(2)T^(-3)I^(-2)]`
`[M^(-1)L^(-2)T^(3)I^(2)]`
`[ML^(3)T^(-3)I^(-2)]`
`[M^(-1)L^(-3)T^(3)I^(2)]`

Solution :IMPEDANCE has the same dimensions as that of a resistance.
Resistance `R= ("Voltage"V)/("Current I")= ([ML^(2)T^(-3)I^(-1)])/([I])= [ML^(2)T^(-3)I^(-2)]`
