The next logical question might be why do these two types of reactance (alternating current resistance) have opposing properties? This is due to the phase shift between current and voltage as it passes through either a inductor or a capacitor. When AC or RF passes through an inductor, the current lags the voltage by 90 degrees. This means the voltage reaches it's highest point 1/4 of the sine wave before the current hits it's peak in the cycle. In the case of the capacitor, voltage lags the current by 90 degrees and creates the opposite effect. This makes everything from certain types of induction motors to tuned circuits possible.
