Time taken to charge the capacitor

The voltage across the capacitor (Vc) is initially zero but it increases as the capacitor charges. The capacitor is fully charged when Vc = Vs. The charging current (I) is determined by the voltage across the resistor (Vs - Vc): Charging current, I = (Vs - Vc) / R (note that Vc is increasing) At first Vc = 0V so the initial current,
