From the instant the voltage is applied, the rate of change of the voltage is high, and if it was to continue in a linear manner, then V C would reach its maximum value in a time equal to one time constant (T), where T (in seconds) is equal to C (in Farads) multiplied by R (in ohms), see fig 4.3.1. above.
