<P> These equations show that a series RL circuit has a time constant , usually denoted τ = L / R being the time it takes the voltage across the component to either fall ( across the inductor ) or rise ( across the resistor ) to within 1 / e of its final value . That is , τ is the time it takes V to reach V ( 1 / e ) and V to reach V ( 1 − 1 / e ) . </P>
