1) The charge on the capacitor after one time constant is about 50% of its maximum value.
2)The voltage on the capacitor after two time constants is about 14% of the maximum value
3)The charge on the capacitor after four time constants is about 98% of the maximum value.
4)The voltage on this capacitor after two time constants is about 100% of its maximum value
5)The charge on the capacitor after one time constant is about 25% of its maximum value.
