C = Q/V If capacitance C and voltage V is known then the charge Q can be calculated by: Q = C V And you can calculate the voltage of the capacitor if the other two quantities (Q & C) are known: V = Q/C Where Reactance is the opposition of capacitor to Alternating current AC which depends on its frequency and is measured in Ohm like resistance.
Another way to look at it is if we have two complex currents a+bj and cj, we get zero phase angle when b=-c (ie when the currents add we get only a real part). This means that we can calculate the imaginary part of the inductor/resistor current and then try to match that with the negative of the imaginary part of the capacitor current. Or:
