What is the dinensions of impedance ?

Options

A. `ML^(2)T^(-3)I^(-2)`
B. `M^(-1)L^(-2)T^(3)I^(2)`
C. `ML^(3)T^(-3)I^(-2)`
D. `M^(-1)L^(-3)T^(3)I^(2)`

Answer

A

Explanation

Impedance has the same dimensions as that of a resistance
`therefore` Resistance `R = ("Voltage V")/("current I")`
`= ([ML^(2)T^(-3)I^(-1)])/([I])=[ML^(2)T^(-3)I^(-2)]`
