For the charging cycle:V_s=V_R+V_C=I R + \int \frac{I dt}{C} where Vs is the voltage from the power supply.
math_failure (math_unknown_error): 0=R \frac{dI}{dt}+ \frac{I}{C},  \frac{dI}{dt}=-\frac{I}{RC} ,  so the solution is I(t)=I_0 e^{-t/(RC)}
at t=0, V_c=0 so I(t=0)=I_0=V_s/R
The result is V_R(t)=I(t) R =V_s e^{-t/(RC)}, V_c(t)=V_s-V_R(t)= V_s (1- e^{-t/(RC)})
