Charging a capacitor with AC voltage

just consider for example the AC voltage where the the voltage is given by V(t) = Vsin(t), for the duration of the positive part of the wave from 0 to pi/2 the capacitor would be ''charging'' for that whole process and be at maximum charge at pi/2.

Why does capacitance affect the charging time of a capacitor?

Second what makes a capacitor "bigger" (in the sense of more capacity). If you take an electron away from a positive charge, it develops a voltage. The more the charges are separated, the higher the voltage is. So the voltage per charge of a capacitor goes up as the plates get more separate*, and the capacitance goes down.

DC Lab

V C is the voltage across the capacitor in V; V S is the voltage of the source in V; t is the time since the closing of the switch in s (tau) is the RC time constant in s .
