An inductor and capacitor are electrically opposite. One is the inverse of the other in terms of how they react to voltage and current. This becomes apparant when you look at the mathematical relationship between them. The time constant for a circuit with a resistor and capacitor is going to be R*C, so it would only make sense for the time constant of a circuit with an inductor and resistor to be L/R.

Because that's the solution that comes out of the differential equation for a circuit with an inductor and a resistor in it.
