The time required for the current flowing in the LR series circuit to reach its maximum steady state value is equivalent to about 5 time constants or 5Ï. This time constant Ï, is measured by Ï = L/R, in seconds, were R is the value of the resistor in ohms and L is the value of the inductor in Henries.
