Suppose that a particular RC series circuit has a time constant of 5.0 seconds. What does that mean in terms of the charging and discharging

Using the RC discharge and recharge table it means that after 5 time constant s there is a maximum current of 99.3% and a maximum voltage of 0.7% while form the charge table there will be a maximum voltage of 99.3% and maximum voltage of 0.7% in the RC CIRCUIT USIng

Vc/Vs= e^ -t/z for discharge and

Vc/Vs = e^(1-t/z) for charging

true tan speed = ang vel x radius
