Which of the followin combinations have the dimensions of time? `L, C, R` represent inductance, capacitance and resistance, respectively. Choose the incorrect option.

Options

A. `RC`
B. `sqrt(LC)`
C. `L//R`
D. `C//L`

Answer

D

Explanation

(4) `RC`: unit : `(v o l t)/(amp) . (amp.s)/(v o l t) = (amp.s)/(amp) = second`
`sqrt(LC) : unit sqrt((v o l t s)/(amp) .(c o u l)/(v o l t))` = second
`(L)/(R ) : (v o l t.s)/(amp) . (amp)/(v o l t)` second
`(C )/(L) : (c o u l)/(v o l t) . (amp)/(v o l t.s) !=` second
