Explain time constant in times of rl and rc series circuit

Hey!!!
Here is your answer__________
There is no difference in the RC time constant whether it be electrical or electronics or even mechanical, chemical or otherwise. There are many analogies but the the RC or FIRST ORDER time constant represents both the rate and ratio of the energy stored in the electric field to that dissipated as heat in doing so. No matter what combination of R and C one chooses for the rate the ratio remains constant. The RC time constant is the time or rate for the capacitor voltage to change by ~63% from the previous or between each such time interval. This is a simple way to avoid elegant but somewhat unnecessary math and a quick way to check in exams and test. Back of the matchbox stuff :)
To see this consider an RC circuit with
the capacitor initially discharged and a voltage of 100V applied.
After time RC Vc=63%*100= 63V after time 2RC Vc =63+63%(100-63) = 63+63%*37 = 63+23.31 = 86.31 V and so on.
